I ran the Import Tool on my java files. (Why oh
why can't it operate on multiple files
simultaneously? I suppose I should file an RFE for
that...)

I don't want to use wildcards, and I don't want to
have FQN's in my source, so I had set the FQN
threshold to 0 (I first set it to 1 - but that
doesn't work. That seems wrong.)

Then I ran the import tool on each file, just
pressing "Finish" as soon as the dialog came up.

For two of my files, it would no longer compile
after running the import tool.  In both cases, the
Import Tool had removed importing the NbBundle
class.  And NbBundle was referenced only in the
initComponents() section generated by the form
module; never outside of the blue areas.

E.g. Import Tool removes necessary/referenced
imports, and it seems to be related to those
imports occurring inside of form builder read-only
regions.
