make run-test TEST=runtime/cds/appcds/cacheObject/DifferentHeapSizes.java
currently fails with:
TEST RESULT: Failed. Execution failed: `main' threw exception: java.lang.RuntimeException: 'Hello World' missing from stdout/stderr

Digging a little deeper reveals that one of the earlier processes that it calls crashes with:

#
# A fatal error has been detected by the Java Runtime Environment:

This only happens on aarch64 for me, x86_64 seems fine. I'll attach the full hs_err.
