As more and more companies develop and deploy multi-threaded Java applications on multi-core hardware, the job of ensuring the quality of these software systems has become more challenging. Multi-threaded software is more complex, impossible to test exhaustively, and introduces a new class of critical concurrency defects—race conditions and deadlocks—that can cause data corruption or system failures.

Coverity Thread Analyzer for Java is the first dynamic analysis solution for multi-threaded Java applications that automatically and predictably detects existing and potential race conditions and deadlocks that can cause deadly application behavior.
