/* * Common Public License Version 0.5 * * THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF * THIS COMMON PUBLIC LICENSE ("AGREEMENT"). ANY USE, * REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES * RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT. * * 1. DEFINITIONS * * "Contribution" means: * a) in the case of the initial Contributor, the * initial code and documentation distributed under * this Agreement, and * * b) in the case of each subsequent Contributor: * i) changes to the Program, and * ii) additions to the Program; * * where such changes and/or additions to the Program * originate from and are distributed by that * particular Contributor. A Contribution 'originates' * from a Contributor if it was added to the Program * by such Contributor itself or anyone acting on such * Contributor's behalf. Contributions do not include * additions to the Program which: (i) are separate * modules of software distributed in conjunction with * the Program under their own license agreement, and * (ii) are not derivative works of the Program. * * * "Contributor" means any person or entity that distributes * the Program. * * "Licensed Patents " mean patent claims licensable by a * Contributor which are necessarily infringed by the use or * sale of its Contribution alone or when combined with the * Program. * * "Program" means the Contributions distributed in * accordance with this Agreement. * * "Recipient" means anyone who receives the Program under * this Agreement, including all Contributors. * * 2. GRANT OF RIGHTS * * a) Subject to the terms of this Agreement, each * Contributor hereby grants Recipient a * no - exclusive, worldwide, royalt - free copyright * license to reproduce, prepare derivative works of, * publicly display, publicly perform, distribute and * sublicense the Contribution of such Contributor, if * any, and such derivative works, in source code and * object code form. * * b) Subject to the terms of this Agreement, each * Contributor hereby grants Recipient a * no - exclusive, worldwide, royalt - free patent * license under Licensed Patents to make, use, sell, * offer to sell, import and otherwise transfer the * Contribution of such Contributor, if any, in source * code and object code form. This patent license * shall apply to the combination of the Contribution * and the Program if, at the time the Contribution is * added by the Contributor, such addition of the * Contribution causes such combination to be covered * by the Licensed Patents. The patent license shall * not apply to any other combinations which include * the Contribution. No hardware per se is licensed * hereunder. * * c) Recipient understands that although each * Contributor grants the licenses to its * Contributions set forth herein, no assurances are * provided by any Contributor that the Program does * not infringe the patent or other intellectual * property rights of any other entity. Each * Contributor disclaims any liability to Recipient * for claims brought by any other entity based on * infringement of intellectual property rights or * otherwise. As a condition to exercising the rights * and licenses granted hereunder, each Recipient * hereby assumes sole responsibility to secure any * other intellectual property rights needed, if any. * * For example, if a third party patent license is * required to allow Recipient to distribute the * Program, it is Recipient's responsibility to * acquire that license before distributing the * Program. * * d) Each Contributor represents that to its * knowledge it has sufficient copyright rights in its * Contribution, if any, to grant the copyright * license set forth in this Agreement. * * 3. REQUIREMENTS * * A Contributor may choose to distribute the Program in * object code form under its own license agreement, provided * that: * a) it complies with the terms and conditions of * this Agreement; and * * b) its license agreement: * i) effectively disclaims on behalf of all * Contributors all warranties and conditions, express * and implied, including warranties or conditions of * title and no - infringement, and implied warranties * or conditions of merchantability and fitness for a * particular purpose; * * ii) effectively excludes on behalf of all * Contributors all liability for damages, including * direct, indirect, special, incidental and * consequential damages, such as lost profits; * * iii) states that any provisions which differ from * this Agreement are offered by that Contributor * alone and not by any other party; and * * iv) states that source code for the Program is * available from such Contributor, and informs * licensees how to obtain it in a reasonable manner * on or through a medium customarily used for * software exchange. * * When the Program is made available in source code form: * a) it must be made available under this Agreement; * and * b) a copy of this Agreement must be included with * each copy of the Program. * * Contributors may not remove or alter any copyright notices * contained within the Program. * * Each Contributor must identify itself as the originator of * its Contribution, if any, in a manner that reasonably * allows subsequent Recipients to identify the originator of * the Contribution. * * * 4. COMMERCIAL DISTRIBUTION * * Commercial distributors of software may accept certain * responsibilities with respect to end users, business * partners and the like. While this license is intended to * facilitate the commercial use of the Program, the * Contributor who includes the Program in a commercial * product offering should do so in a manner which does not * create potential liability for other Contributors. * Therefore, if a Contributor includes the Program in a * commercial product offering, such Contributor ("Commercial * Contributor") hereby agrees to defend and indemnify every * other Contributor ("Indemnified Contributor") against any * losses, damages and costs (collectively "Losses") arising * from claims, lawsuits and other legal actions brought by a * third party against the Indemnified Contributor to the * extent caused by the acts or omissions of such Commercial * Contributor in connection with its distribution of the * Program in a commercial product offering. The obligations * in this section do not apply to any claims or Losses * relating to any actual or alleged intellectual property * infringement. In order to qualify, an Indemnified * Contributor must: a) promptly notify the Commercial * Contributor in writing of such claim, and b) allow the * Commercial Contributor to control, and cooperate with the * Commercial Contributor in, the defense and any related * settlement negotiations. The Indemnified Contributor may * participate in any such claim at its own expense. * * * For example, a Contributor might include the Program in a * commercial product offering, Product X. That Contributor * is then a Commercial Contributor. If that Commercial * Contributor then makes performance claims, or offers * warranties related to Product X, those performance claims * and warranties are such Commercial Contributor's * responsibility alone. Under this section, the Commercial * Contributor would have to defend claims against the other * Contributors related to those performance claims and * warranties, and if a court requires any other Contributor * to pay any damages as a result, the Commercial Contributor * must pay those damages. * * * 5. NO WARRANTY * * EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE * PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT * WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR * IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR * CONDITIONS OF TITLE, NO - INFRINGEMENT, MERCHANTABILITY OR * FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely * responsible for determining the appropriateness of using * and distributing the Program and assumes all risks * associated with its exercise of rights under this * Agreement, including but not limited to the risks and * costs of program errors, compliance with applicable laws, * damage to or loss of data, programs or equipment, and * unavailability or interruption of operations. * * 6. DISCLAIMER OF LIABILITY * EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER * RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY * FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, * OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION * LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF * LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT * (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT * OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE * OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE * POSSIBILITY OF SUCH DAMAGES. * * 7. GENERAL * * If any provision of this Agreement is invalid or * unenforceable under applicable law, it shall not affect * the validity or enforceability of the remainder of the * terms of this Agreement, and without further action by the * parties hereto, such provision shall be reformed to the * minimum extent necessary to make such provision valid and * enforceable. * * * If Recipient institutes patent litigation against a * Contributor with respect to a patent applicable to * software (including a cros - claim or counterclaim in a * lawsuit), then any patent licenses granted by that * Contributor to such Recipient under this Agreement shall * terminate as of the date such litigation is filed. In * addition, If Recipient institutes patent litigation * against any entity (including a cros - claim or * counterclaim in a lawsuit) alleging that the Program * itself (excluding combinations of the Program with other * software or hardware) infringes such Recipient's * patent(s), then such Recipient's rights granted under * Section 2(b) shall terminate as of the date such * litigation is filed. * * All Recipient's rights under this Agreement shall * terminate if it fails to comply with any of the material * terms or conditions of this Agreement and does not cure * such failure in a reasonable period of time after becoming * aware of such noncompliance. If all Recipient's rights * under this Agreement terminate, Recipient agrees to cease * use and distribution of the Program as soon as reasonably * practicable. However, Recipient's obligations under this * Agreement and any licenses granted by Recipient relating * to the Program shall continue and survive. * * Everyone is permitted to copy and distribute copies of * this Agreement, but in order to avoid inconsistency the * Agreement is copyrighted and may only be modified in the * following manner. The Agreement Steward reserves the right * to publish new versions (including revisions) of this * Agreement from time to time. No one other than the * Agreement Steward has the right to modify this Agreement. * * IBM is the initial Agreement Steward. IBM may assign the * responsibility to serve as the Agreement Steward to a * suitable separate entity. Each new version of the * Agreement will be given a distinguishing version number. * The Program (including Contributions) may always be * distributed subject to the version of the Agreement under * which it was received. In addition, after a new version of * the Agreement is published, Contributor may elect to * distribute the Program (including its Contributions) under * the new version. Except as expressly stated in Sections * 2(a) and 2(b) above, Recipient receives no rights or * licenses to the intellectual property of any Contributor * under this Agreement, whether expressly, by implication, * estoppel or otherwise. All rights in the Program not * expressly granted under this Agreement are reserved. * * * This Agreement is governed by the laws of the State of New * York and the intellectual property laws of the United * States of America. No party to this Agreement will bring a * legal action under this Agreement more than one year after * the cause of action arose. Each party waives its rights to * a jury trial in any resulting litigation. * * * * (C) COPYRIGHT International Business Machines Corp. 2001, 2002 */ /* * Copyright 2009 Sun Microsystems, Inc.
