> The fix updates JVMTI FollowReferences implementation to report references > from virtual threads: > - added heap scanning to report unmounted vthreads; > - stacks of mounted vthreads are splitted into 2 parts (vittual thread stack > and carrier thread stack), references are reported with correct thread > id/class and object tags/frame depth; > - common code to handle stack frames are moved into separate class;
Alex Menkov has updated the pull request incrementally with one additional commit since the last revision: Fixed test - replaced obsolete java.util.concurrent.ForkJoinPool.common.parallelism with jdk.virtualThreadScheduler.parallelism; - added check that vthreads are mounted/unmounted; - disabled testing of JNI locals for unmounted thread as native call pins vthread and does not allow it to unmount. ------------- Changes: - all: https://git.openjdk.org/jdk/pull/13254/files - new: https://git.openjdk.org/jdk/pull/13254/files/8108f217..841f5a78 Webrevs: - full: https://webrevs.openjdk.org/?repo=jdk&pr=13254&range=02 - incr: https://webrevs.openjdk.org/?repo=jdk&pr=13254&range=01-02 Stats: 45 lines in 1 file changed: 30 ins; 0 del; 15 mod Patch: https://git.openjdk.org/jdk/pull/13254.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/13254/head:pull/13254 PR: https://git.openjdk.org/jdk/pull/13254
