8366951: Test runtime/logging/StressAsyncUL.java is timing out

[jdksjolen]

Hi,

This test times out sometimes. This has been known to be caused previously by a resource-constrained execution environment. It may also be because of a race between async logging initialization and the loggers (see JDK-8362282).

This PR reduces the stress by changing the log level from trace to debug. This changes the amount of logging from 48M to 6.6M, a significant reduction.

The goal with the test was to find out if there are any bugs in the stalling mode by running it in a 'stressful' situation over a long time. The stalling mode was integrated in 2025-02-26 (see #22770 ). I therefore believe that relaxing this test is in our interest, as it reduces the stress on our CICD infra.

Makes sense; I also wonder if trace-level log can be reduced a bit -- the current amount is not very usable, IMO.

[lkorinth]

Looks good to me!

[dholmes-ora]

Good fix. There's always a risk that "all" logging will reach a point where we get swamped with output, and that happened with AOT trace level.

[jdksjolen]

thanks!
