My guess is that object with null reference cant give a Compiler error. Is anything wrong with the statement if SO please explain why is the compiler halting Thank You.
First of all, you should do what the message is telling you, which is to file a bug report with Sun about this bug in the javac compiler that you have found.
The problem is likely the "t += null" statement. The "+=" operator is defined for very types, namely numerical types and strings. Using it with any other types (like you are doing here) won't work.
