Concurrency bugs include race conditions, code reordering, field visibility issues, live locks, deadlocks and performance related bugs, such as contention and starvation. In this article Java Specialist Dr. Heinz Kabutz examines two threading bugs he discovered in the core Java libraries.
Writing Java software that correctly and safely makes use of concurrency requires careful thought. Software that incorrectly accounts for concurrency can contain intermittent defects that elude even the most rigorous testing regimes. Static analysis tools can analyze source code or compiled bytecode to discover latent bugs hidden within code, long before it is executed.
