Field watch tests updated to be executed with virtual threads when virtual test thread factory enabled.I added jdk.test.lib.thread.TestThreadFactory to created test threads so they support virtual thread factory jtreg plugin.
It might makes sense to use it in different tests so virtual threads are tests more extensively. There is JDIThreadFactory in nsk/sharejdi which I copied. I am going to update JDI tests to use jdk.test.lib.thread.TestThreadFactory later. ------------- Commit messages: - 8339638: Update vmTestbase/nsk/jvmti/*Field*Watch tests to use virtual thread factory Changes: https://git.openjdk.org/jdk/pull/20897/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=20897&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8339638 Stats: 75 lines in 5 files changed: 63 ins; 0 del; 12 mod Patch: https://git.openjdk.org/jdk/pull/20897.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/20897/head:pull/20897 PR: https://git.openjdk.org/jdk/pull/20897
