Causing a break into the debugger [message #1768954]

When I programmed using C/C++ under Windows using Microsoft Visual Studio, I could cause my program to simulate hitting a breakpoint by putting a call to DebuBreakpoint() in my code. This was simpler than setting a conditional breakpoint when the condition was complex. If this was called during a non-debug run, it created an exception which stopped execution, but it was wonderfully handy during development. All it did was execute an INT3 instruction, which is the stock debugger breakpoint for the x86 architecture. I would like to do something analogous when running under Eclipse. Currently, I do it by

if(complex_test_for_validity)
      {
       System.out.print(all kinds of stuff);
       System.out.println(); // set breakpoint here
      }

But that seems silly. I set the conditions that would lead to the tests and breakpoint via command-line options that would not normally be known to an end user. Is there any means of replacing the println with a call so that my code looks more like

if(...)
   {
    ...stuff...
    DebugBreak();
   }

?
The goal is to avoid searching for the correct line each time.

I just spent an hour trying different search keys, and came up dry.

I suggest you throw a specific exception and set an exception breakpoint.
