Description

I'm trying to run the javascript obfuscator from the maven-plugin-javascript, and it breaks when it reaches a regular expression, for example for this snippet:

mytext.split(/=/,2)

the obfuscator breaks and dumps this:

Error processing file:stuff/utils.js to file:blackstuff/utils.js
org.apache.myfaces.trinidadbuild.plugin.javascript.obfuscator.javascript15parser.ParseException: Encountered "/=" at line 52, column 42.
Was expecting one of:

on the face of it it looks like the obfuscator doesn't understand basic regular expression syntax as documented here: http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Guide:Regular_Expressions
