[wtp-releng] Build compiler warnings too aggressive?

[Cameron Bateman <cameron.bateman@xxxxxxxxxx>]

The JSF team is in the midst of cleaning up code warnings.  I thought I 
had resolved all the warnings caught by the webtools build, but one 
remains that is not caught by Eclipse/JDT at all.  This is the use of 
imported classes only in JavaDocs.  For example,  we have a warning in 
one of our modules as below.  It is true that this class is not used in 
the code but it *is* used in the JavaDoc and generates JavaDoc warnings 
if the import is removed (though it does not break the build).  Indeed, 
Ctrl-Shift-O will add the import back in if I remove it.

   import org.eclipse.swt.SWTException;
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The import org.eclipse.swt.SWTException is never used
