The following three tests timed out in the JDK21 CI:

com/sun/jdi/SourceNameFilterTest.java
com/sun/jdi/SetLocalWhileThreadInNative.java
com/sun/jdi/OomDebugTest.java

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

Please note that SourceNameFilterTest.java timed out during the
compilation phase of the test.

The WhileThreadInNative.java failure looks like the test
finished based on this mess: "Debuggee: received STOP message"
but the JTREG agent still timed out.

The OomDebugTest.java log looks like a "normal" ran-out-of-time
test failure.
