Description

This bug was distilled from a conversation with Xibin Zeng about http://issues.apache.org/jira/browse/BEEHIVE-899 .

Repro:

• Create the following page flow controller:

---

@Jpf.Controller(
catches=

{ @Jpf.Catch(type=Exception.class, method="handleIt") }

)
public class Controller extends PageFlowController
{
@Jpf.Action
public Forward begin()

{ throw new IllegalStateException("intentional"); }

@Jpf.ExceptionHandler
public Forward handleIt(Exception ex, String actionName, String message, Object formBean)

{ throw new UnsupportedOperationException("another intentional exception"); }

}

---

• Hit it in the browser.

EXPECTED: go to the normal unhandled-exception page, with a stack trace for the IllegalStateException (the original exception), and also see the stacktrace for the UnsupportedOperationException in the logs.

ACTUAL:
java.lang.ClassNotFoundException: handleIt
