Just had it pop up again.
Using Warnings-NG 5.0.0, analysis-model-api 5.0.2, Jenkins 2.164.3, and all the other plugins patched up to the version as of writing this note.
Note, had just did an inplace restart of Jenkins to patch analysis-model-api
But the output of the stage where I had all the static analysis bits in it looks like:
Stage : Start - (2 min 2 sec in block) Static Analysis Console Output Success
Static Analysis - (2 min 2 sec in block) Success
General Build Step - (24 sec in self) Console Output Success
