Gary Gregory commented on XALANJ-2573:
--------------------------------------

Depending on compatibility, we should consider using Java's own RE pacakge instead.

> Current build of xalan-2.7.1.jar includes seemingly jakarta-regexp version 1.2:
> Name: org/apache/regexp/
> Comment: Java Regular Expression package 
> Specification-Title: Java Regular Expression package 
> Specification-Vendor: Apache Software Foundation 
> Specification-Version: 1.2
> Implementation-Title: org.apache.regexp
> This is pretty far from the latest regexp available - 1.5.
> Can you update the build to include latest ?
> The consequences are that some long time fixed regexp bugs are getting exposed though
xalan, like :
> Caused By: org.apache.regexp.RESyntaxException: Syntax error: Too many bracketed closures
(limit is 10)
>         at org.apache.regexp.RECompiler.syntaxError(RECompiler.java:253)
>         at org.apache.regexp.RECompiler.closure(RECompiler.java:1014)
>         at org.apache.regexp.RECompiler.branch(RECompiler.java:1151)
>         at org.apache.regexp.RECompiler.expr(RECompiler.java:1203)
