Additional open source projects

The following software is being made available by the University of Maryland and the FindBugs project. The software is still preliminary, and needs volunteers to help mature it.

• Multithreaded test case, a framework designed to make it easy to create test cases for concurrent software in which multiple threads must coordindate their activity to perform a test (e.g., testing a concurrent blocking queue, with one thread that blocks when it trys to add to a full queue, and another thread that unblocks the first by removing an element).
• Checked uncontended lock, an implementation of the Java 5 Lock and ReadWriteLock interfaces that throw exceptions if they detect lock contention. These locks are designed to be used for debugging, and can be used in places where you don't believe you need to use a lock but want to verify that at runtime.
