Hi Claes, did you try instead of having a field 'internal' to inline the class check (this.getClass() == PrintStream.class) at every call site you are reading that field ? for a method like println(), the VM has to do a class check (if CHA is defeated) before entering the method println so the JIT might be able to remove the check this.getClass() == PrintStream.class because it already know at that point that the current class is PrintStream.
interesting idea - I'll try it out. I don't expect it to make much of a difference in my current (trivial) tests, but perhaps in a slightly more contrived setup. happy new year! /Claes
