Guidelines
CON01-J. Ensure visibility of shared variables and atomicity of composite operations
CON02-J. Always synchronize on the appropriate object
CON03-J. Do not use background threads during class initialization
CON04-J. Use the private lock object idiom instead of intrinsic synchronization
CON05-J. Ensure that threads do not fail during activation
CON06-J. Do not defer a thread that is holding a lock
CON07-J. Ensure atomicity of thread-safe code
CON08-J. Do not invoke a superclass method or constructor from a synchronized region in the subclass
CON09-J. Do not call overridable methods from synchronized regions
CON10-J. Methods that override synchronized methods must also possess synchronization capabilities
CON11-J. Do not assume that elements of an array declared volatile are volatile
CON12-J. Avoid deadlock by requesting locks in the proper order
CON12-J. Do not try to force thread shutdown
CON13-J. Do not let the "this" reference escape during object construction
CON15-J. Ensure actively held locks are released on exceptional conditions
CON16-J. Do not expect sleep() and yield() methods to have any synchronization semantics
CON17-J. Avoid using ThreadGroup APIs
CON18-J. Always invoke wait() and await() methods inside a loop
CON19-J. Use notifyAll() instead of notify() to resume waiting threads
CON20-J. Never apply a lock to methods making network calls
CON21-J. Facilitate thread reuse by using Thread Pools
CON22-J. Use the correct form of the double-checked locking idiom
CON23-J. Address the shortcomings of the Singleton design pattern
CON24-J. Use a unique channel to acquire locks on any file
CON25-J. Ensure atomicity when reading and writing 64-bit values
