Hi,

We are running lots of junit 5 tests ( +5000) but we are always arriving in a out of memory for the maven surefire plugin as it seems it is keeping a lot of info into the heap space, we raised internally already to -Xmx8GB but seems still not enough, do you see any improvements we still can make?
we already remove big parts of our logging, but seems that it is still filling up memory

No source file or test is named. Start by reproducing the out-of-memory failure with JUnit 5 and more than 5,000 tests under the Maven Surefire plugin, using the attached memory evidence and reported heap settings as context; done means identifying the retained memory and verifying a fix or actionable configuration guidance.
