deadlock
When two threads interfere in such a way that neither can continue. Sometimes called deadly embrace or Mexican standoff. There is absolutely nothing you can do with a deadlocked thread. You cannot stop it, you cannot interrupt it, you cannot tell it to stop trying to get a lock, and you also cannot tell it to let go of the locks that it owns. This is one of the criticism in Doug Lea’s book about the primitive monitor-based locking mechanisms. Once you try to get a lock, you will forever try and never give up. The concurrency handling mechanisms of Doug’s book are now in the java.util.concurrent package of JDK 1.5.

Bloch and Lea especially have very good reputations in concurrent programming. This is the dream team to write such a book. See the companion website with code examples, a sample chapter, errata etc..

432 pages. You can read it online. This is the book on Threads and concurrent programming. The only problem with it is does not cover the new java.util.concurrent package which the author helped design.

The classic way it happens is by thread 1 locking object a then trying to get a lock on object b, while thread 1 gets a lock on object b and tries to get a lock on object a. The simplest way to avoid this is to always acquire locks in canonical order.
