"The Java programming language neither prevents nor requires detection of deadlock conditions." \[[JLS 05|AA. Java References#JLS 05]\]. Deadlocks can arise when two or more threads request and release locks in different orders. Consequently, to avoid deadlock, locks should be acquired and released in the same order and synchronization should be limited to where it is absolutely necessary. For instance, to avoid deadlocks in an applet, the {{paint()}}, {{dispose()}}, {{stop()}}, and {{destroy()}} methods should not be synchronized because they are always called and used from dedicated threads. |
Deadlocks can also arise when two or more threads are waiting for each other to release resources such as database connections. The advice of this guideline also applies to these cases.
