Description
We see four tests failing on AIX because they can not attach:

runtime/jni/terminatedThread/TestTerminatedThread.java

These terminate with "TEST FAILURE: AttachCurrentThread() returns: -1"
vmTestbase/nsk/jvmti/scenarios/jni_interception/JI05/ji05t001/TestDescription.java 
vmTestbase/nsk/jvmti/scenarios/jni_interception/JI06/ji06t001/TestDescription.java 
vmTestbase/nsk/jvmti/SetJNIFunctionTable/setjniftab001/TestDescription.java

The tests just fail reproducible if executed.
Comments
[jdk21u-fix-request] Approval Request from Christoph Langer Requesting backport of the test fix of JDK-8219652 for better test coverage on AIX. I melted two minor exclude list corrections into the main change. Testing: GHA and SAP CI. Risk is low.

This is likely the same issue addressed by JDK-8303549 for another test - the default pthread stack size is too small. It also appears the minimum stack size for this platform is set too small.

Thanks for the clarification. 'hotspot/runtime' is the right place.

These tests are exercising jni AttachCurrentThread. Not jdi attach-on-demand.

If these are really attach-on-demand mechanism issues, then this bug belongs in hotspot/svc and not hotspot/runtime or hotspot/jvmti.
