serviceability/jvmti/vthread/ContStackDepthTest/ContStackDepthTest.java failing in loom repo with Xcomp

loom repo, tier4. This test fails intermittently with:

# Internal Error (<top>/workspace/open/src/hotspot/share/prims/jvmtiThreadState.cpp:601), pid=11953, tid=12203
# assert(_cur_stack_depth == num_frames) failed: cur_stack_depth out of sync _cur_stack_depth: 14 num_frames: 18

With -Xcomp runs it seems to fail more frequently, the stack trace is the same:
