I'm getting the following NullPointerException when runing the `maven-rulecheck-maven-plugin` on my project.
Run "mvn clean test-compile" in order to reproduce the bug on the drools-compiler project on this commit on this branch.
(The stack trace is being printed out because I recompiled 3.0.1 with debug statements).
From what I've been able to debug, the `type` variable in a `CFG` instance is not always set, so it seems like a null-check should be added to the code (see associated PR).
This seems to be happening for rules that involve references to local variables. I haven't been able to pinpoint any other causes.
