    [ https://issues.apache.org/jira/browse/LANG-686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13005142#comment-13005142 ] 

Maurizio Cucchiara commented on LANG-686:
-----------------------------------------

I'm not sure this is a bug. The IllegalStateException was throwned because your substitution pattern triggers a (though little) recursion, it's a kind of prevention, in order to avoid StackOverflowError
