NullPointerException when third-party update site not installed

[imagejan]

When you run the CLIJ2 assistant (Plugins › ImageJ on GPU (CLIJ2) › Start CLIJ2-Assistant), don't have the ImageJ 3D Suite update site active, and then right-click on the canvas of the active image, the following gets logged to the console:

[ERROR] Cannot create plugin: class='net.haesleinhuepf.clijx.imagej3dsuite.ImageJ3DSuiteConnectedComponentsLabeling', name='CLIJx_imageJ3DSuiteConnectedComponentsLabeling', priority=0.0, enabled=true, pluginType=CLIJMacroPlugin
Exception in thread "Run$_AWT-EventQueue-0" java.lang.NullPointerException

... and no context menu appears.

Maybe the failure of PluginService to create a plugin instance can be handled more gracefully, without disrupting the right-click context menu.

Hey Jan,

that's a good point. Can you confirm that the bug is NOT happening if the clijx-assistant-extensions update site is NOT enabled?

Thanks!

Best,
Robert
