Well, there's a null value somewhere that there shouldn't be. There should
be some better log messages somewhere that point you to the exact line of
code where you're having issues.

I don't know how related to the error you're seeing this is, but in
Guacamole 1.0.0 we raised the minimum Java version required to 1.8. 1.8
has been out for a LONG time, and itself won't be supported much longer, so
we thought it was pretty safe to move up to that. You might try with JDK
1.8 or better and see if that works.
