JHipster generated JUnit testing: "java.lang.OutOfMemoryError: GC overhead limit exceeded" error when running tests

Question

I have a JHipster application, v5.3.0. Monolith. Maven. Elasticsearch. 3 entities.

I run:

./mvnw clean test

5 minutes or more of test execution follows and then the following error:

java.lang.OutOfMemoryError: GC overhead limit exceeded

and test hangs.

Any ideas or solutions?

Answer 1

If you're using JUnit 5.3.0, this may be due to a known bug in that release.

If so, upgrading to JUnit 5.3.1 should fix it.
