[jboss-jira] [JBoss JIRA] (AS7-4597) Slave host error handling in a managed domain should not assume the context failure description node can be converted to ModelType.OBJECT

Mon Apr 30 11:36:17 EDT 2012

    [ https://issues.jboss.org/browse/AS7-4597?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12688863#comment-12688863 ] 

Brian Stansberry commented on AS7-4597:
---------------------------------------

Looking at the candidates, I agree that pushToServers is the likely one, since the last 2 are called on non-2-phase ops and the 2nd should be called after this error happens.

Perhaps a total failure or rollback (which is what results in the pushToServers line being called) is resulting in a failure description in the final result of the first phase invocations on the slave HCs. Perhaps those failure descriptions are actually irrelevant. Best way to know is to reproduce.

> The relevant logic at DomainFinalResultHandler.collectHostFailures(DomainFinalResultHandler.java:158) does this:
> context.getFailureDescription().get(HOST_FAILURE_DESCRIPTIONS).set(hostFailureResults);
> The IAE indicates the ModelNode returned by context.getFailureDescription() has already been initialized to some other ModelType (probably ModelType.STRING) and thus can't be used to store a failure description with a ModelType.OBJECT structure.
> We need to figure out why the failure description was already initialized in order to decide how best to deal with this.
