Data Source

This report is based on simple comparison of all public and protected APIs of the java.* and javax.* packages of JDK builds 25-ea+11-1205-open and 21.0.6+7-LTS-tem. 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.
