extends Exception

`RuntimeException` is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.

A method is not required to declare in its `throws` clause any subclasses of `RuntimeException` that might be thrown during the execution of the method but not caught.

Direct instances of this exception class are not bound to any context and can be passed between contexts without any restrictions. Objects created and returned by the methods of this class are owned by the caller. In particular, a call to the `Throwable.getMessage()` returns a String instance bound to the owner context of the caller.

See Runtime Environment Specification for the Java Card Platform, Connected Edition, chapter 7 for details regarding transfer of ownership.

Since:
  JDK1.0, CLDC 1.0, Java Card 3.0
