MNG-6713 was a fix to support wildcard exclusions. Before they were always ignored, since it was an exact match of the wildcard with the groupId or artifactId, which would always be false.
The improvement contains a bug, because in case of a wildcard, it does a direct match, ignoring following exclusions.
WORKAROUND: Start the exclusion-list with the explicit groupID and artifactId, ending with the exclusions containing wildcards. This will restore the behavior as before
