Description Rob Stryker 2013-03-25 16:22:01 UTC

Description of problem:
Using AS 7.2 / EAP 6.1 client jars to connect to AS 7.0.x fails with hang. 


Version-Release number of selected component (if applicable):
 jboss-as-controller-client-7.2.0.Final-redhat-3.jar,
 jboss-as-logging-7.2.0.Final-redhat-3.jar,
 jboss-as-protocol-7.2.0.Final-redhat-3.jar,
 jboss-dmr-1.1.6.Final-redhat-1.jar,
 jboss-logging-3.1.2.GA-redhat-1.jar,
 jboss-marshalling-1.3.16.GA-redhat-1.jar,
 jboss-marshalling-river-1.3.16.GA-redhat-1.jar,
 jboss-remoting-3.2.15.GA-redhat-1.jar,
 jboss-sasl-1.0.3.Final-redhat-1.jar,
 jboss-threads-2.1.0.Final-redhat-1.jar,
 xnio-api-3.0.7.GA-redhat-1.jar,
 xnio-nio-3.0.7.GA-redhat-1.jar


How reproducible:
Occasionally, if with random management actions. Every time when performed with attached eclipse project. 

Steps to Reproduce:
1. Download and import into eclipse the plain java project attached to https://issues.jboss.org/browse/AS7-6779
2. Set project classpath to use jars from as7.2 folder and Launch an AS 7.0.x server outside of eclipse, OR,  set project classpath to use jars from as7.1 folder and launch an EAP 6.1 outside of eclipse. 
3. Run the new project's main class. 
  
Actual results:
The Main class hangs. In this case the client is a simple Main class. However, when similar code is run as an eclipse plugin, it could freeze the workspace. 

Expected results:
The methods complete without error.

I assume you are also seeing something like this in the client?

Attaching a jstack of the process.  I am not seeing what you are expecting. 

This stack is what I see when using 7.1 jars against eap6.1.

using jboss-remoting-3.2.16.GA will resolve the issue.

Where would I download specific versions of jboss-remoting? The last version on the remoting page is 3.1.0.Beta2 which was added in 2010.  http://www.jboss.org/jbossremoting/downloads

Aha, well i'd just take the artifact from maven then: https://repository.jboss.org/nexus/content/groups/public/org/jboss/remoting3/jboss-remoting/3.2.16.GA/

Max Rydahl Andersen <max.andersen> made a comment on jira AS7-6779

Emanuel, what does the fix entail ? 

Which servers can we expect to continue to use this remoting client with ?

All AS 7.1.x/7.2.x + EAP 6.0.x/6.1.x and upwards ? 

If yes we will just use the old ones for AS 7.0 and use these new ones for future updates.
