question: protected synchronized void checkInit ( ) { if ( nonceGeneration == null ) { nonceGeneration = new ZWaveSecureNonceTracker ( getNode ( ) ) ; } if ( threadLock == null ) { threadLock = new Object ( ) ; } if ( payloadEncapsulationQueue == null ) { payloadEncapsulationQueue = new ConcurrentLinkedQueue < ZWaveSecurityPayloadFrame > ( ) ; } }
target:  Checks the fields which are marked with XStreamOmitField as they will be null upon deserialization from a file TODO: Can't we find a better way to do this than calling it each time through the loop?
