The following test timed out in the JDK24 CI:

Here's a log file snippet:

There's no indication in the log about *why* the test timed out
and it looks like there are no artifacts saved. I could not find
any other timeout sightings like this one in Mach5.

I'm starting this bug off in client-libs/javax.sound for initial triage.
I suspect we'll have to keep our eyes open and see if it happens
to reproduce.
