Description

While testing 0.16-SNAPSHOT, I identified rat is much longer to execute than with 0.15.

Release 0.16.1 will publish a quickfix that guards expensive regex-based matching, but further analysis may happen to improve performance even more.

[e-mail] started quick analysis - see details at https://lists.apache.org/thread/4qyjkh5fv464n1f60p1o44rb6yhdg5gj
