Exception while pfxprobe try to write down a detected issue

Some reports failed to be written in a gitlab ci run. To reproduce it simply apply pfxprobe to a non well formated groovy file.

Not sure if it is related to #1

Here is the stack trace I obtained.

Exception in thread "main" org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '[{type=issue, engine_name=pfxprobe, check_name=file-not-formatted, description=[minor] File is not auto-formatted.
