All Implemented Interfaces:

java.io.Serializable

public class RMIException
extends com.gemstone.gemfire.GemFireException

This exception is thrown when an exception occurs during a remote method invocation. This RuntimeException wraps the actual exception. It allows distributed unit tests to verify that an exception was thrown in a different VM.

     VM vm0 = host0.getVM(0);
     try {
       vm.invoke(this.getClass(), "getUnknownObject");

     } catch (RMIException ex) {
       assertEquals(ex.getCause() instanceof ObjectException);
     }
 

Note that special steps are taken so that the stack trace of the cause exception reflects the call stack on the remote machine. The stack trace of the exception returned by getCause() may not be available.
