Deadlock during some tests in CI #97

Open niloc132 opened 2 years ago

niloc132 commented 2 years ago

Some CI tests that run junit tests can hang indefinitely, ending with logging only this line:

[INFO] Building: java-assertions/pom.xml

or some other test meant to try out unit tests - haven't observed other failures of this type.

The build.log for the test itself ends with:

Might be back (or never left more likely), but is much less common now: https://github.com/Vertispan/j2clmavenplugin/runs/4973238357?check_suite_focus=true https://github.com/Vertispan/j2clmavenplugin/runs/4973112237?check_suite_focus=true
