Multiple WFLYEJB0043: A previous execution of timer ... when slow server start in JBoss EAP 7

Issue

• Multiple WFLYEJB0043: A previous execution of timer ... when slow server start in JBoss EAP 7
• EJB Timer WFLYEJB0043: A previous execution of timer ... when slow server start

When starting the JBoss instance with an EJB timer for example below, it looks like the application with the timer may be initialized but cannot start because the server has not stabilized and once JBoss is stabilized logs WFLYEJB0043 even though the timer was not previously (or should not have been previously running).

  @Schedule(second="*/10", minute="*", hour="*", persistent=false)
  public void timeout() {
    log.info("Timer fired at 10 sec interval");
  }
