The following test timed out in the JDK19 CI:

runtime/Thread/AsyncExceptionTest.java

Here's a snippet from the log file:

result: Error. Program `/opt/mach5/mesos/work_dir/jib-master/install/jdk-19+17-1108/linux-x64-debug.jdk/jdk-19/fastdebug/bin/java' timed out (timeout set to 480000ms, elapsed time including timeout handling was 499163ms).

I'm starting this bug as a P2 since this is a Tier1 failure.
