  • Method Details

    • rethrowIfFatal

      public static void rethrowIfFatal(Throwable throwable) throws Error, RuntimeException
      It is important never to catch all Throwables. Some like InterruptedException should be rethrown. Based on scala.util.control.NonFatal. This method should be used with care.

      If the Throwable is fatal, it is rethrown, otherwise, this method just returns. The input throwable is thrown if it is an Error or a RuntimeException. Otherwise, the method wraps the throwable in a RuntimeException and throws that.

      Parameters:
      throwable - to check
      Throws:
      Error - the input throwable if it is fatal
      RuntimeException - the input throwable if it is fatal - throws the original throwable if is a RuntimeException. Otherwise, wraps the throwable in a RuntimeException.
