Data Source

This report is based on simple comparison of all public and protected APIs of the java.* and javax.* packages of JDK builds 17.0.13+11-tem and 15.0.2+7-adpt. It does not make statements about compatibility.

For the latest Java versions the corresponding CSRs (Compatibility & Specification Review) are linked for a quick reference to find out about the reasoning of the change.
