The following three tests failed in the JDK19 CI:

runtime/NMT/JcmdBaselineDetail.java
runtime/NMT/HugeArenaTracking.java
runtime/cds/appcds/jvmti/InstrumentationTest.java

Here's a snippet from the JcmdBaselineDetail.java log file:

The HugeArenaTracking.java and InstrumentationTest.java failures
have similar log file snippets.
