This report is based on simple comparison of all public
and
protected
APIs of the java.*
and javax.*
packages of JDK builds 23+37-tem 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.
