Data Source

This report is based on simple comparison of all public and protected APIs of the Java SE packages of JDK builds 27-ea+10-857-open and 19.0.2+7-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.
