Several issues have been reported related to attaching a thread to the JVM. They were reported for AIX, but may not be limited to it.
Attaching works when creating a new pthread with sufficient stack size set by pthread_attr_setstacksize. An example has been implemented byJDK-8320309.
Failures were reported when using the primordial thread, using default stack size or using C++ std::thread. One problem has been reported here: https://github.com/adoptium/adoptium-support/issues/997
There was a SIGSEGV instead of a helpful error message.
Other JVMs like J9 are not affected by this problem. The problem seems to be caused by the hotspot code which creates stack guard pages. We should probably avoid that in the future. Stack banging will need to get replaced by explicit checks for that.
