lzgrillo: Error at import plugins

GUEST: After starting NB under JDK 9 EA (b147), I was offered to import a couple plugins from my NB 8.2 installation.  I checked "Darcula" and clicked on import.  Crash.

GUEST: Tried to import plugins from 8.2 instance into dev build.  Aside from a couple plugins that were supported, I also checked "Darcula" and hit "Import".  That's when exception occured.

GUEST: During import of plugins from Netbeans 8.2 stable

brettryan: Accepted an import for the h2 module.

GUEST: fresh install:
imported plugins from prev version, and wanted to restart.

tveimo: selected some plugins to import from previous installation. failed when agreeing to restart.
