When using the AceJump shortcut, the following error occurs:

Somehow, you were able to activate AceJump with no open projects! How is this possible? :)

Your error is caused by this line. When I wrote it I remember thinking, "#190 could never happen":

ProjectManager.getInstance().openProjects[0]

Can you provide any hints for how to reproduce this error? Thanks @rocketraman!

[rocketraman]

@breandan Now how did I do that?? :-) I just tried to replicate it and no luck -- it is working fine. I'll go ahead and close this for now, and if it happens again I'll keep better notes of what I was doing.

@breandan Re-opening! I just reproduced this on the latest version:

I have an open project but it is a Node.JS project and has no java sources. The active editor contains a json file. I also tried an Asciidoc (.adoc) and some Javascript source (.js). Same error for all.
