jtreg plugin for IntelliJ IDEA - report of NullPointerException

[Chris W. Johnson]

I'm using IntelliJ IDEA 2020.1.2 (Ultimate Edition), build #IU-201.7846.76. I have no idea whether the issue is specific to the version of IntelliJ, because this is my first attempt to use the jtreg plugin.

BTW, I encountered a build problem on line 232 of "JTRegServiceConfigurable":

            return antTarget instanceof MetaTarget ? AntIcons.MetaTarget : AntIcons.Target;

The problem is the "AntIcons" class doesn't include a "Target" field (I'm guessing it did in the past). I made the build work substituting "AntIcons.Task", on the assumption the worst effect would be an inappropriate icon appearing in the GUI.

Unfortunately, the plugin produces the NullPointerException show below during IntelliJ startup, before I ever see its GUI. Enclosed are the logs and diagnostic data gathered by IntelliJ.

Thanks for your efforts.
