> This PR fixes a synchronization issue in the test: > `test/hotspot/jtreg/serviceability/jvmti/vthread/PopFrameTest` > > The method `notifyAtBreakpoint()` can notify the `TestTask` thread when it > has not reached an expected breakpoint yet. > The fix is to add a call to the method `ensureAtBreakpoint()` one more time > in the `B2` sub-test. It is needed after the top-most frame was popped with > the JVMTI `PopFrame`, and the target thread needs to reach the breakpoint > again after its execution was resumed. > > The time is very intermittent. At least, I was not able to reproduce the > timeout failure in thousands of mach5 runs with the `-Xcomp` option. > > Testing: > - Run the test > `test/hotspot/jtreg/serviceability/jvmti/vthread/PopFrameTest` thousands > times in mach5
