Exception in thread "management task-3" java.lang.LinkageError: loader constraint violation

[priya_asthana15]

Hi,

I need urgent help to fix the following issue.

I am using Wildfly10 .Final  in domain mode. I downloaded source code of corresponding wildfly-core-2.0.10.Final that is integrated with Wildfly10.0.0.Final

I added few log messages in controller module in wildfly-core-2.0.10.Final .

After I swapped wildfly-controller-2.0.10.Final.jar in modules/system/layers/base/org/jboss/as/controller/main/     and  started Wildfly in domain mode , I am getting the following errors while starting servers

Can you tell us why you went with this approach instead of just using the pre-built WildFly? Were you trying to debug something in the code, if so, what? There are other ways to do that instead of downloading source code to add logger messages and trying to build it.

It would probably be better if you would rebuild whole core and build wildfly 10 with this core.

also make sure you use 2.0.10.Final not 2.1.0.Final as there ware some API changes.

[priya_asthana15]

Yes I am trying to debug -

For my product requirement, I need to modify server and HostController source code.

1. After modification, I re-build wildfly-core-2.0.10.Final .

2. Swap old jars of HostController and server with new jars created in step1.

3. Deploy on servers fail . Failure message is "WFLYHC0153: Channel closed"

To debug step 3, I wanted to add few more logs in controller.

Please suggest what would be a better way to integrate modified wildfly-core-2.0.10.Final with wildfly10.0.0.Final.

I have set logging as DEBUG in domain.xml.

I am using 2.0.10.Final version of wildfly-core.

Can you please tell how do I build wildfly10 with wildfly-core ?

[priya_asthana15]

I tried to deployed using jboss-cli.sh

Although the content is copied in domain/data/content/  but it is not being pushedToServers.

WFLYHC0153: Channel closed exception is thown

[priya_asthana15]

I have resolved this issue.

So closing it for now.Thanks,
