[David Lloyd (JIRA)]

David Lloyd updated WFLY-2800:
------------------------------

    Steps to Reproduce: 
Deploy a session bean that requires a transaction and have it throw a org.jboss.util.deadlock.ApplicationDeadlockException.

or

Add the following test case to org.jboss.invocation.test.ChainedInterceptorTestCase and run mvn test on the jboss-invocation subproject.

{code}
    /**
     * What if again re-invokes a chained interceptor?
     */
    @Test
    public void testAgainWithChain() throws Exception {
        Method method = ChainedInterceptorTestCase.class.getMethod("echo", String.class);
        InterceptorContext context = new InterceptorContext();
        context.setMethod(method);
        context.setTarget(this);
        context.setParameters(new Object[] { "testAgain" });

        Interceptor again = new Interceptor() {
            private int num = 2;
            @Override
            public Object processInvocation(InterceptorContext context) throws Exception {
                StringBuilder result = new StringBuilder();
                while ((num--) > 0)
                    result.append(context.proceed());
                return result;
            }       
        };      
        Interceptor interceptor1 = Interceptors.getChainedInterceptor(createMyInterceptor("1"), createMyInterceptor("2"), Interceptors.getInvokingInterceptor());
        Interceptor interceptor2 = Interceptors.getChainedInterceptor(createMyInterceptor("3"), createMyInterceptor("4"), again, interceptor1);

        String result = (String) interceptor2.processInvocation(context);
        String expected = "3#4#1#2#Echo testAgain1#2#Echo testAgain";
        assertEquals(expected, result);
    }       
}
{code}

>            Reporter: Eric van der Maarel
>
> When you invoke and re-invoke org.jboss.invocation.InterceptorContext.proceed() from an interceptor in a chain of interceptors and the interceptor to be (re-)invoked is a org.jboss.invocation.ChainedInterceptor or WeavedInterceptor, a CannotProceedException is thrown.
> This bug has been described and analysed in the context of the ejb3 container, on the forum at https://community.jboss.org/message/853547.
