Your line numbers doesn't match the ones in GIFEncoder source, maybe because of JIT optimization. To get the good line numbers, you should try to run your program in interpreted mode with the -Xint Java option.
Anyway, I would bet that the output stream you gave in GIFEncoder constructor is null...
