Is there asm nop equivalent in java?

Question

When I program C/C++ with Visual Studio I often use __asm nop; command to insert a noop code in order to have something to break on. For instance:

You can just put in any arbitrary assignment statement that doesn't do anything, e.g.

if (someCondition()) {
  int t=0;
}

The debugger will be happy to break on this. Since t is local to the block, it can't possibly have any side effects (and will get JIT-compiled out of existence in production code).

Alternatively, you can write a static function which has a breakpoint permanently set inside it, so you can just do:

if (someCondition()) {
  breakPoint();
}
