Potential NPE in TimerData

When timerConfig is null, following TimerData constructor will throw NPE.

public TimerData(long id, EjbTimerServiceImpl timerService, String deploymentId, Object primaryKey, Method timeoutMethod, TimerConfig timerConfig)

{ this.id = id; this.timerService = timerService; this.deploymentId = deploymentId; this.primaryKey = primaryKey; this.info =timerConfig.getInfo(); this.persistent = timerConfig.isPersistent(); this.timer = new TimerImpl(this); this.timeoutMethod = timeoutMethod; }
