The following path expressions aren't being parsed & interpreted correctly:

1) "default://(*.cnd)[/jcr:content@jcr:data]" will not match (i.e. will not be triggered) for "default://images.cnd/jcr:content@jcr:data"
2) "default://(*.class)/jcr:content[@jcr:data] => /classes/$1" will create for a matched input of: default:/TestClass.class the following output: default://classes/TestClass.class/TestClass.class
