The following two tests failed in the JDK17 CI:

java/nio/channels/DatagramChannel/ManySourcesAndTargets.java
java/nio/channels/DatagramChannel/InterruptibleOrNot.java

I'm filing a single bug for these two failures because the test
executions overlapped in this sighting.

DatagramChannel/ManySourcesAndTargets.java failed due to a
timeout and here's a snippet from the log file:

#section:main
