In NetBeans 6.5 rc2, "Profile main project" becomes disabled without explanation if the "Hibernate Support" plug-in is
uninstalled.

Steps to reproduce:
1. install NetBeans 6.5 rc2
2. Tools | plug-ins | installed plug-ins
   Uninstall many plug-ins, including Hibernate Support (to trim footprint)
3. restart
4. Try to run Profile | Profile Main Project

Actual: 
During step 2, there was no indication that Java Profiler depends on Hibernate.
In step 4, Profile Main Project is disabled without explanation.

Expected:
During step 2, expected warning that uninstalling Hibernate Support will disable Java Profiler, or expect that Java
Profiler would be uninstalled if it depends on Hibernate Support.

Notes:
This might have been the cause of issue 122454.  I was unable to diagnose the problem then.  

This time I was able to diagnose it by reinstalling netbeans (which was itself not straightforward) and noticing Profile
Main Project was fixed, then uninstalling plug-ins one-by-one until I found the dependency.  This took a couple hours so
I don't expect users who run into this problem will do it.

(Reinstalling netbeans was not straightforward because when I just ran the installer, it refused to reinstall over an
existing installation [said all modules were already installed, even though some plug-ins were uninstalled], and when I
ran the uninstaller it did not remove everything, so when I ran the installer after uninstalling, it refused to install
into the same directory [said directory is not empty].  It finally installed after deleting directory.)
