Jakarta Persistence defines a standard for management of persistence and object/relational mapping in Java(R) environments.

• Most of the Jakarta Persistence project source code is licensed under the Eclipse Public License (EPL) v2.0 and Eclipse Distribution License (EDL) v1.0.; see the license information at the top of each source file.
• The source code for the Jakarta Persistence Specification project is licensed under the Eclipse Public License (EPL) v2.0 and GNU General Public License (GPL) v2 with Classpath Exception; again, the license is in each source file.
• The binary jar files published to the Maven repository are licensed under the same licenses as the corresponding source code; see the file META-INF/LICENSE.txt in each jar file.

You’ll find the text of the licenses in the workspace in various LICENSE.txt or LICENSE.md files. Don’t let the presence of these license files in the workspace confuse you into thinking that they apply to all files in the workspace.

You should always read the license file included with every download, and read the license text included in every source file.
