This is a 'getting started' problem. [Cardea IU-135.1019]
I was able to resovle the plugin runtime configuration [ Error: Could not create the Java Virtual Machine. ] by simplfying the plugin project's default settings. [Need to open an issue for that]
I now have a 'do nothing' plugin, created using the wizards for a new plugin project, and for a new action [new menu bar action]. This is loosely based on the 'getting started with plugin development' wiki page.
When the plugin is run, I promptly get a 'License Upgrade Needed' dialog box.
Is that normal? [Not seeing the license for the host IJ instance?]
