Recommendations
CON00-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
CON03-J. Do not assume that elements of an array declared volatile are volatile
CON04-J. Do not call overridable methods from synchronized regions
CON05-J. Use a unique channel to acquire locks on any file
CON06-J. Do not subclass Thread if you can use a Runnable instead
Rules
CON30-J. Synchronize access to shared mutable variables
CON31-J. Always invoke the wait() method inside a loop
CON32-J. Use notifyAll() instead of notify() to resume waiting threads
CON33-J. Address the shortcomings of the Singleton design pattern
CON34-J. Avoid deadlock by requesting locks in the proper order
CON35-J. Do not try to force thread shutdown
CON36-J. Always synchronize on the appropriate object
CON37-J. Never apply a lock to methods making network calls
CON38-J. Ensure atomicity of thread-safe code
CON39-J. Ensure atomicity of 64-bit operations
CON40-J. Do not let the "this" reference escape during object construction
CON41-J. Do not use file locks for arbitrating file access at the thread level
CON42-J. Ensure actively held locks are released on error conditions
