No idea?
Comment 5 zmirc 2015-08-25 09:35:01 UTC 
It just happened to me on NB DEV 201508230002.

That's what I did: 
I was in Projects left window, then I selected a Java file from my project, then CTRL+C to copy it, then I selected the package that contained that class, then CTRL+V to make a copy of the previously copied Java file, then this error appeared.

Hard to fix without a reproducible test case. Any steps to reproduce would be welcome.

Code completion? "if (it."
Comment 9 Dusan Balek 2016-06-29 12:46:52 UTC 
Should be fixed together with #262392.
