Error on undeploy/deploy

I just tried with 1.0.0.M3 and it gets rid of the loop and the NPE that was giving, it still gives the WebappClassLoader exception:

And now I'm getting *another* endless loop...

Are you using 1.0.0.M3 or the latest snapshot?

-Mark

I do have the latest snapshot on my workspace, but since I'm using maven to build and the top pom has in the dependencyManagement

<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-core</artifactId>
<version>1.0.0.M3</version>
</dependency>

I assume that on runtime is the 1.0.0.M3 that's being used.

This probably has to do with the implementation I'm trying to do of a synchronous-that-falls-down-to-asynchronous-with-correlationId-when-timedout messages, because the same error (or at least a similar one) is occurring elsewhere besides hot-redeploying...

It's very difficult to debug with time outs and futures!

BTW, I also using modified versions of RequestReplyTemplate, MessageStore, RetrievalBlockingMessageStore ans SimpleMessage, but except for the first all I did was adding a iterator.
