Is there any way to breakpoint inside the tested classes?
===

Here's my scenario:

 1. I have an Android service (`CoreService`)
 2. I use `ServiceTestCase<CoreService>` to test it	
 3. `CoreService` spawns a thread and instantiates several classes that have listeners/callbacks on them.

Is there any way to set up breakpoints in the spawned threads and/or callbacks and have JUnit stop at these? It only stops at breakpoints set in the JUnit project or `CoreService` class.
