Call Graph seems blocked. Java project too big?

[jkleiser]

I just wanted to try Call Graph on our rather big Java 8 project. When I specify the Directory and hit Run, Call Graph finds 5421 functions, but then seems to get stuck. I see that this exception has been caught:

What may be the reason for this?
