These changes have all been undone since the > test now runs the same when using virtual threads as with platform threads.
Chris Plummer has updated the pull request incrementally with one additional commit since the last revision: Restore forceEarlyReturn() platform thread behaviour to only throw NativeMethodException and get rid of assert. A future CR/CSR will resolve the issue of OPAQUE_FRAME sometimes not meaning NativeMethodException for platform threads. ------------- Changes: - all: https://git.openjdk.org/jdk/pull/14167/files - new: https://git.openjdk.org/jdk/pull/14167/files/89d3e110..93a18437 Webrevs: - full: https://webrevs.openjdk.org/?repo=jdk&pr=14167&range=01 - incr: https://webrevs.openjdk.org/?repo=jdk&pr=14167&range=00-01 Stats: 6 lines in 1 file changed: 2 ins; 3 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/14167.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/14167/head:pull/14167 PR: https://git.openjdk.org/jdk/pull/14167
