There is a stack walk in JvmtiExport::post_exception_throw() that has safepoints in it. This trips up the stack watermark code. This patch adds a RAII object to JvmtiExport::post_exception_throw() that keeps the thread and its stack fully processed throughout the function. Testing: tier1-7 of ZGC tests on linux x86_64 debug and manual testing of the test that failed.
