Please, review a fix for:   https://bugs.openjdk.java.net/browse/JDK-8222072 Webrev:   http://cr.openjdk.java.net/~sspitsyn/webrevs/2019/8222072-jvmti-GenerateEvents.1/ Summary:   The JVMTI GenerateEvents() must send CompiledMethodLoad events only to the agent which called it.   However, it sends events to all agents (jvmti environements) which violates the JVMTI spec.   The webrev above fixes this issue and adds new jtreg test:     test/hotspot/jtreg/serviceability/jvmti/GenerateEvents Testing:   Mach5 submission for:    - JVMTI tests: open/test/hotspot/jtreg/vmTestbase/nsk/jvmti    - new test: test/hotspot/jtreg/serviceability/jvmti/GenerateEvents Thanks, Serguei
