Guidelines
CON07-J. Do not invoke a superclass method or constructor from a synchronized region in the subclass
CON01-J. Avoid using ThreadGroup APIs
CON02-J. Facilitate thread reuse by using Thread Pools
CON10-J. Do not assume that elements of an array declared volatile are volatile
CON08-J. Do not call overridable methods from synchronized regions
CON05-J. Use a unique channel to acquire locks on any file
CON09-J. Methods that override synchronized methods must also possess synchronization capabilities
CON05-J. Do not defer a thread that is holding a lock
CON04-J. Ensure that threads do not fail during activation
CON03-J. Use the private lock object idiom instead of intrinsic synchronization
CON00-J. Synchronize access to shared mutable variables
CON31-J. Always invoke wait() and await() methods inside a loop
CON32-J. Use notifyAll() instead of notify() to resume waiting threads
CON33-J. Address the shortcomings of the Singleton design pattern
CON11-J. Avoid deadlock by requesting locks in the proper order
CON12-J. Do not try to force thread shutdown
CON01-J. Always synchronize on the appropriate object
CON37-J. Never apply a lock to methods making network calls
CON06-J. Ensure atomicity of thread-safe code
CON14-J. Ensure atomicity of 64-bit operations
CON13-J. Do not let the "this" reference escape during object construction
CON02-J. Do not use background threads during class initialization
CON15-J. Ensure actively held locks are released on exceptional conditions
CON43-J. Use the correct form of the double-checked locking idiom
CON16-J. Do not expect sleep() and yield() methods to have any synchronization semantics
