------------------------------------------------------------

If cause is UndeclaredThrowableException, could cause.getCause() be null?
If so, it is better to move this before checking if cause is null; otherwise, it is fine with
me.

+                  if (cause != null && cause instanceof UndeclaredThrowableException)
{
+                    cause = cause.getCause();
+                  }
+                  if (cause == null){
+                    throw new RuntimeException(
+                      "Proxy invocation failed and getCause is null", e);
