Request for integrating #225950 - Adding Groovy class to Web App Project messes up compilation class path

Bug link:
http://netbeans.org/bugzilla/show_bug.cgi?id=225950

Description of the bug:
If anyone with Web or Ejb application (based on Ant, not Maven) creates 
any Java EE class inside (Servlet, Session bean etc.) plus add a Groovy 
class it results in uncompilable application because the groovy compiler 
which wrapps standard javac does not contain Java EE classes on it's 
classpath.

Impact assessment:
This might impact on many users! Anyone with listed types of application 
who creates Groovy class or script inside ends up with uncompilable 
application. It is not even easy to revert the changes made by file wizard.

Risk assessment:
Changeset only extend the classpath for groovy-build scripts and put the 
Java EE classes to the compile process. IMHO there is no risk.
