[jboss-jira] [JBoss JIRA] (AS7-4084) Implement JMX-style management access to Infinispan components

[Richard Achmatowicz (JIRA)]

    [ https://issues.jboss.org/browse/AS7-4084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12729893#comment-12729893 ] 

Richard Achmatowicz commented on AS7-4084:
------------------------------------------

Implemented the code that Tristan provided into the Infinispan subsystem recently refactored into resources.

Encountered the following problem:

<quote>
Infinispan and JGroups gather statistics in certain associated services (e.g. TransactionManager, RpcManager,...). These services are installed
at boot time, but not started until someone deploys a clustering application which uses them. So, if I try to read one of their read-only
attributes before a deployment has occurred, I throw an OperationFailedException with a message saying that the required service
has not been started. This works fine and seems to be the right way to proceed.

On the other hand, there is a smoke test case BasicOperationsUnitTestCase.testRecursiveReadIncludingRuntime() which seems to assume that all reads of runtime-only resources will succeed.
</quote>

Is it really the case that every read of a read-only attribute should always succeed? If so, what is the best way to work around this? Can I
somehow return an informational message instead of throwing an exception? Checking these issues with Emanuel M.
