> To test ForceEarlyReturn command for NO_MORE_FRAMES case the test creates > ThreadStartEventRequest with SUSPEND_ALL policy and requests debuggee to > start new thread. > If debuggee JVM starts some internal threads before the request is cleared > (i.e. we have several ThreadStart events), 2nd event suspends debuggee again > and the test fails with timeout. > The change adds THREAD_ONLY modifier to the ThreadStartEventRequest to > generate event only for desired thread. > It requires thread ID, so debuggee was updated to create Thread object in > advance, debugger reads the thread ID from static field (it does not need to > be static, but Debugee class has convenient methods to retrieve class ID and > static field value). > > Testing: 100 runs of the test on > windows-x64-debug,linux-x64-debug,macosx-x64-debug with > JTREG_TEST_THREAD_FACTORY=Virtual, with and without "-XX:+UseZGC > -XX:+ZGenerational"
