/**
 *  Allows masking of interrupt flag if previously the flag is already set. Does nothing otherwise.
 *
 *  Typical use:
 *
 *   *  InterruptUtil interruptUtil = new InterruptUtil(context);
 *
 *  try {
 *    interruptUtil.maskInterruptFlag();
 *    someOtherThread.join(delay);
 *  } catch(InterruptedException e) {
 *    // reachable only if join does not succeed within delay.
 *    // Without the maskInterruptFlag() call, the join() would have returned immediately
 *    // had the current thread been interrupted previously, i.e. before entering the above block
 *  } finally {
 *    interruptUtil.unmaskInterruptFlag();
 *  }
 *  
 *  @author Ceki Gulcu
 *  @since 1.2.2

 * @deprecated This internal logback API is not supported by AEM as a Cloud Service.
