Currently I need to specify each method that I want to get white-listed. This is extremely cumbersome. It would be helpful if I can use some kind of wildcards to specify the whitelist of a plug-in.

This basically is related to JENKINS-25804. Why do I need to add every method on String to be whitelisted? It would be much simpler to say method * of String so that all methods on this immutable class get white listed (or even better: everything of String or Matcher, etc. is whitelisted). It shouldn't be hard to gather the matching methods using reflection.
