This is the line code in our app calling the builder which produces 
a core exception from jdt build manager.

try
        {
               ResourcesPlugin.getWorkspace().build(IncrementalProjectBuilder.INCREMENTAL_BUILD, progressMonitor);
        }
        catch (CoreException e)
        {

Please has the fix also on top of eclipse 3.0.2 for WAS602. The installation of our product failed on redhat because this bug, and we have no workaround of it.
Thanks,
