NB 7.2 HR integration review request: #210053 - "Uncompilable source code" when running freshly cleaned and built Web Project

Description:
http://netbeans.org/bugzilla/show_bug.cgi?id=210053

When running a project using compile or deploy on save, the execution 
fails with RuntimeException - Uncompilable source code in some cases. 
One of the cases, fixed by this fix, is related to invoking methods 
whose return types are erroneous.

Risk assessment: low risk.

The patch is reviewed by Dusan Balek and verified by Jirka Prox.
