The following tests failed in the JDK15 CI and generated an
hs_err_pid file for the out of memory condition like this:

# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 643632 bytes for Chunk::new

serviceability/sa/TestDefaultMethods.java
serviceability/sa/TestClhsdbJstackLock.java
serviceability/sa/TestClassDump.java
serviceability/sa/ClhsdbPrintAll.java
serviceability/sa/ClhsdbJstackXcompStress.java

Two additional tests failed with other memory related
failure modes:

serviceability/sa/TestInstanceKlassSize.java
serviceability/sa/TestHeapDumpForInvokeDynamic.java

TestInstanceKlassSize.java:

LingeredApp failed to start: java.io.IOException: App exited unexpectedly with -1073741502

TestHeapDumpForInvokeDynamic.java:
