  The NullPointerException (NPE) hides the underlying cause.
  
  Client is also using:
  This occurs without ClearCase and
  with ClearCase using the ClearCase Remote
  Client (CCRC) plug-in to save or checkout a file.
  Although not clear, the error supposedly occurs w/o NPE
  
  Possible Workaround:
  
   make sure Clients/Users have write access to ?workspace-dir?\.m
  etadata\.plugins\org.eclipse.ui.workbench\workingsets.xml .
  
  (Note:  If they are using CCRC, there is a chance they may have
  set their workspace dir to be within a ClearCase-controlled area
  , in which case they will not have write access to that location
  .  But that is just one possible cause of this problem...
  esepacilly since this was a new install, and CCRC appears to be
  involved, so if these developers are new to ClearCase usage and
  RAD development, they may have made that mistake.)
  

Local fix

Problem summary

• The call to save the working set was not being done on the
  UI thread.  If an error occurred during saving, a
  NullPointerException would be entered into the .log.
  

Problem conclusion

• The code needed to be modified to save the working set on
  the UI thread. This allows for proper display of the error
  dialog.
  Fixed in Rational Application Developer V7.5.5
