User Comments:
GUEST: Filling in constructor args.

frederic.gendebien: I was creating an anonymous class of type Comparator and when I used completion to generate the body I received a NPE

GUEST: Was finding and replacing TreeSet with ArrayList. Error just popped up then. I can't see a major issue though.

GUEST: delete some java class, and open the java file which need dependent the deleted classes, error reported

The code uses T_, T__, ... to simulate high order generics. That seems to be crashing netbeans parser, even though javac compiles it fine.
