offender:

public int m(int a, int b) {

for (b = methodA(b)+1; ; current++)
{
  int i = methodB(b);
  if (i == -1) 
  {
     return -1;
  } else {
     return methodC(b);
  }
}

there is probably some flag to turn this behavior off, but it's not the default behavior of the sun javac. I don't really care, people shouldn't write dead code. but it's a bug. a warning should have been enough I guess.
>How-To-Repeat:
compile it with standard flags.
>Fix:
remove the incrementer from the for loop.
