  None

In the specified configuration, the response transformers on the http:outbound-endpoint are not applied. If I move the transformer to the consoleOut transformers, I get the 'desired' result (the exception is thrown), but outside this test I would like to work with a response transformer (which of course does not throw exceptions).

The Java Code for the transformer:

import org.mule.api.transformer.TransformerException;
import org.mule.transformer.AbstractTransformer;

public class ExceptionThrower extends AbstractTransformer {

@Override
protected Object doTransform(Object src, String encoding)
throws TransformerException { throw new RuntimeException("got here"); }

}
