Description
# To suppress the following error report, specify this argument
# after -XX: or in .hotspotrc:  SuppressErrorAt=/jvmtiRawMonitor.cpp:377
#
# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (open/src/hotspot/share/prims/jvmtiRawMonitor.cpp:377), pid=31520, tid=31753
#  assert(__the_thread__->is_Java_thread()) failed: Only JavaThreads can be interruptible
#
# JRE version: Java(TM) SE Runtime Environment (14.0+15) (fastdebug build 14-ea+15-611)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (fastdebug 14-ea+15-611, compiled mode, sharing, compressed oops, g1 gc, linux-amd64)
# Problematic frame:
# V  [libjvm.so+0x1129f54]  JvmtiRawMonitor::raw_wait(long, bool, Thread*)+0x334

This is triggered by the changes in JDK-8230424, but we need to see how an interruptible wait arises here.
