NPE when calling operations on inactive modcluster subsystem
------------------------------------------------------------
Key: AS7-3027
URL: https://issues.jboss.org/browse/AS7-3027
Project: Application Server 7
Issue Type: Bug
Components: Clustering
Affects Versions: 7.1.0.Beta1b
Reporter: Jesse Jaggars
Assignee: Paul Ferraro
Despite not being able to 'see' the modcluster subsystem as illustrated below:
[domain@localhost:9999 subsystem] pwd
/host=master/server=server-one/subsystem
[domain@localhost:9999 subsystem] ls
cmp datasources ee ejb3
infinispan jacorb jaxrs jca
jdr jmx jpa logging
mail messaging naming osgi
remoting resource-adapters sar security
threads transactions web webservices
weld
I can still call methods on that subsystem. However when I do this, there is a
NullPointerException thrown by the operation code.
[domain@localhost:9999 /]
/host=master/server=server-one/subsystem=modcluster/:read-proxies-configuration
{
"outcome" => "failed",
"result" => undefined,
"failure-description" => "JBAS014749: Operation handler failed:
null",
"rolled-back" => true
}
And the log/stacktrace is:
[Server:server-one] 11:39:45,518 ERROR [org.jboss.as.controller.management-operation]
(pool-1-thread-3) JBAS014612: Operation ("read-proxies-configuration") failed -
