Since PMD could output some "warnings" on stderr
it would break parsing of correct output.

Example output:
WARNUNG: This analysis could be faster, please consider using Incremental Analysis: https://pmd.github.io/pmd/pmd_userdocs_getting_started.html#incremental-analysis

Started PMD without the patches and get an error. Started PMD with the patch and get correct results.
