The `VirtualThread` static field `notifyJvmtiEvents` is not set correctly in cases JVMTI agents are loaded into running VM. It is because an extra call to java_lang_VirtualThread::init_static_notify_jvmti_events() is needed. This function is called once at the VM initialization, so this extra call is not necessary for agent loaded at startup.
Testing: New test is added: `test/hotspot/jtreg/serviceability/jvmti/vthread/VirtualStackTraceTest` This test is failed without fix and passed with it. TBD: run all JVMTI and JDI test in mach5. ------------- Commit messages: - fixed traling whitespace in jvmtiExport.cpp - 8296324: JVMTI GetStackTrace truncates vthread stack trace for agents loaded into running VM Changes: https://git.openjdk.org/jdk/pull/11204/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=11204&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8296324 Stats: 182 lines in 3 files changed: 181 ins; 0 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/11204.diff Fetch: git fetch https://git.openjdk.org/jdk pull/11204/head:pull/11204 PR: https://git.openjdk.org/jdk/pull/11204
