Most annoying code snippet ever:

void CompileTask::print_tty() {
  ttyLocker ttyl; // keep the following output all in one block
  // print compiler name if requested
  if (CIPrintCompilerName) tty->print("%s:", CompileBroker::compiler_name(comp_level()));
    print(tty);
}

The indent of print "suggests" it is under the if but of course it's not. Use braces!
