The fix removes finalization cleanup from vmTestbase. The last to classes that use it are: DebugeeBinder and SocketIOPipe. The DebugeeBinder is used in jdi and jdwp tests and is always linked with debuggee process. So the DebugeeProcess.waitFor() is the good place to close binder and free all it's resources. The SocketIOPipe is used directly in AOD tests where it should be closed after test execution.
The OPipe (child of SocketIOPipe) also used in jdi and jdwp tests where it is connected directly in tests. However is also connected with debuggee and could be closed in DebugeeProcess.waitFor(). The VMOutOfMemoryException001 test is fixed to release some memory after throwing OOME so Sytem.exit() could complete successfully. Previously some memory freed during VM shutdown hook. I verified that cleanup printed that corresponding 'close' method has been already called before VM shutdown phase for debugger process. Additionally, run all vmTestbase tests to verify there are no failures, ------------- Commit messages: - removed finalization Changes: https://git.openjdk.org/jdk/pull/19505/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=19505&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8307824 Stats: 291 lines in 10 files changed: 14 ins; 271 del; 6 mod Patch: https://git.openjdk.org/jdk/pull/19505.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/19505/head:pull/19505 PR: https://git.openjdk.org/jdk/pull/19505
