(your javascript plugin) Ow JavaScript 0.2.7

create a new java project, add javascript facet, open project properties select javascript | closure -> see error

[bytesandwich]

I have a fairly complicated project, so I just wanted to see if the issue occurs on a fresh install/project

I noted that I don't receive this error if it is just a javascript project.

[vtst]

Thanks for the bug report. I just fixed the issue in the code base. The fix will be available in the next release.

[bytesandwich]

Thank you for maintaining the super useful plugin.
