Thread Weaver is a framework for writing multi-threaded unit tests in Java. It provides mechanisms for creating breakpoints within code, and for halting execution of a thread when a breakpoint is reached.

The newest version!

 * loads a new instance of this class to perform the actual test run.
 * 
 * Note that because the test classes are loaded in a separate class loader, all

 * BaseTestWrapper simplify this process by having a single entry point that the
 * BaseThreadedTestRunner can invoke. The implementation can then make compiled
 * calls into the test classes.
