Thanks. I don't know why I didn't remember to use this.

What seems to happen is that we have java.lang.SecurityManager
that directly uses java.awt.AWTPermission. This means that the
object file for the *entire* java.awt package gets pulled in,
since we compile a package at a time, which leads to a whole
lot of new references that need to be satisfied and so on
ad nauseum.

Now I can see how JToolBar gets pulled in.

Thanks,
Ranjit.
