During mainline change pre-integration testing the test crashed in CI on ARM64 MacOS:
runtime/cds/appcds/aotClassLinking/AOTLoaderConstraintsTest.java

Preliminary assigning to runtime to look since it happened during startup with -XX:AOTMode=create.

[~iklam] May be we should exclude running the test with -Xcomp.
