Junit plugin appears hung during Pipeline step

We have roughly 8,000 tests and have been using the junit step with no issue. However, when using the snippet generator, I was able to add in the Test Stability feature but now either the junit step is taking many orders of magnitude longer (1 hr+ where usually it only takes a couple of seconds) or we are completely deadlocked. Also of note, the junit step gets called in parallel as we run our tests in parallel node blocks.
