This commit stopped errorprone errors/warnings being recognised by the Warnings Next Generation plugin - I don't understand why anyone would want this behavior (if you don't want to see errorprone warnings, don't use it) but if it must be kept I think it should be a flag which can be optionally disabled.

If the regex in edu.hm.hafner.analysis.parser.JavacParser were changed to remove the trailing $ it would then match multi-line errorprone errors if passed directly, but if passed the lines individually would continue to work as expected in the previous version.
