Bridge between JBoss 4.2.1 JBM to HornetQ in EAP 6.1.0 GA

[mastergenny]

Hi,

we implemented a jms-bridge in JBoss 4.2.1 to HornetQ in an EAP 6.1 following this instructions. https://community.jboss.org/wiki/BridgeJMSMessagesFromAS5ToAS7

It runs perfectly. But there is a problem. We need to guarantee that the bridge is correct after network errors. We used wanEM to simulate network troubles. After it we have problems.

The bridge tries to reconnect without success. The following stacktrace is shown. It looks like the classloader lost the context-impl from th SAR but we don't know why and why now!

Stacktrace:

1. javax.naming.NoInitialContextException: Cannot instantiate class: org.jboss.naming.remote.client.InitialContextFactory [Root exception is java.lang.ClassNotFoundException: No ClassLoaders found for: org.jboss.naming.remote.client.InitialContextFactory]

Hi,

I removed the following from the jboss-service.xml in the SAR.

<loader-repository-config>java2ParentDelegation=false</loader-repository-config>

After it I started the test of network errors and the bridge show me this stacktrace.

I am sure that org.xnio.Options is part of the jar.

I believe the problem you're hitting is a defect either in the bridge itself or in JBoss AS itself related to the thread which handles the failure and classloading.  I believe this has been resolved upstream via https://issues.jboss.org/browse/WFLY-2499.
