> Degrade Thread.suspend/resume to throw UOE unconditionally. > > Another step in the removal of this deadlock prone mis-feature from the > user-facing API. Thread.suspend/resume have been deprecated since JDK 1.2 > (1998) and terminally deprecated since Java 14. ThreadGroup.suspend/resume > were degraded to throw UOE in Java 19. As of Java 19, Thread.suspend/resume > continues to work for platform threads but throws UOE for virtual threads. > The next step is to degrade both methods to throw UOE for all threads. A > corpus search of 19M classes in 113k JAR files found only 22 classes using > these methods so this change is unlikely to be disruptive. > > The change requires some minor adjustments to the JVM TI and JDWP > specifications, and a minor update to the JDI docs. > > Leonid Mesnik is working on > [PR10351](https://github.com/openjdk/jdk/pull/10351) to remove/replace the > last few usages of Thread.suspend/resume from the hotspot tests (most of > these can use JVMTI SuspendThread/ResumeThread).
