Description James Moody CLA 2002-04-18 11:24:44 EDT 
M5, Linux

Opened new workbench. Do NOT open the java perspective.
Opened CVS perspective, loaded team plugins from dev.eclipse.org.
Switch to resource perspective.
Import binary plugins for all except the team plugins.
Finish.
The first project (ant core) appears in the workspace, and I get the following npe:

Comment 1 James Moody CLA 2002-04-18 11:25:56 EDT 
Autobuild was off at the time.
Comment 2 James Moody CLA 2002-04-18 11:27:07 EDT 
After switching to the Java perspective, deleting the single project, and
importing them all again, it worked fine.
Comment 3 Philipe Mulet CLA 2002-04-19 07:05:29 EDT 
Offending line is:
  this.getJavaModel().getWorkspace().run(operation, monitor);

which means that the JavaModel wouldn't be initialized at this point.
Comment 4 Philipe Mulet CLA 2002-04-19 07:55:07 EDT 
Fixed by making getJavaModel() lazily allocate the model if not already 
existing. Also discarded getJavaModel(workspace).

Fixed
