Coverage generation minion exited abnormally! (UNKNOWN_ERROR) pitest 1.9.4

[nicenemo]

Unknown error with pitest 1.9.4 but not with 1.8.1 or 1.7.x

Our build works up to version 1.8.1 of pitest but not with any later versions.

We run pitest with:

mvn org.pitest:pitest-maven:mutationCoverage
With versions 1.9.0 up to 1.9.4 Pitest immediately fails.
I think there is something wrong with my pom.xml or Java setup but not sure what.
I Added a redacted pom.xml file and part of the log file.

What am I doing wrong and and did miss in the documentation or is missing in the documentation?

        Pitest is a mutation testing tool. enable it to see coverage missing not caught by SonarQube /Jaccoco.
        It helped in finding/solving a few bugs and eliminating some code. Also for adding reggression tests it is really useful.

        See https://www.pitest.org for more info.

Same result with the Zulu 17 JDK.

[nicenemo]

Also unsetting my MAVEN_OPTS dit not help.

When upgrading to 1.9.0 the pitest-junit5-plugin needs to be upgraded to 1.0.0 due to an api change. This is most likely the issue.

It is mentioned in the release note, but perhaps needs to be clearer?

As a result of #1040 any external pitest test plugins (eg JUnit 5, TestNG, arcmutate accelerator) must be updated to a compatible version (1.0.0) when upgrading.

I will add another property to my pom.xml
thanks.
