Node count fails when Cache.toString() called between @Inject and @Start methods. --------------------------------------------------------------------------------- Key: JBCACHE-1487 URL: https://jira.jboss.org/jira/browse/JBCACHE-1487 Project: JBoss Cache Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 3.0.3.GA Reporter: Galder Zamarreno Assignee: Manik Surtani Fix For: 3.1.0.GA Node count fails when Cache bean is deployed via MC and TRACE is enabled on org.jboss.kernel: 2009-03-03 21:40:51,505 ERROR [AbstractKernelController] (main) Error installing to Instantiated: name=CacheClusterA1 state=Described java.lang.UnsupportedOperationException: Not supported in UnversionedNode at org.jboss.cache.AbstractNode.getChildrenDirect(AbstractNode.java:277) at org.jboss.cache.mvcc.NodeReference.getChildrenDirect(NodeReference.java:272) at org.jboss.cache.invocation.NodeInvocationDelegate.getChildrenDirect(NodeInvocationDelegate.java:163) at org.jboss.cache.DataContainerImpl.numNodes(DataContainerImpl.java:461) at org.jboss.cache.DataContainerImpl.getNumberOfNodes(DataContainerImpl.java:438) at org.jboss.cache.DataContainerImpl.toString(DataContainerImpl.java:394) at org.jboss.cache.DataContainerImpl.toString(DataContainerImpl.java:372) at org.jboss.cache.invocation.CacheInvocationDelegate.toString(CacheInvocationDelegate.java:144) at java.lang.String.valueOf(String.java:2615) at org.jboss.util.JBossStringBuilder.append(JBossStringBuilder.java:114) at org.jboss.dependency.plugins.AbstractControllerContext.toString(AbstractControllerContext.java:362) MC is printing the cache content in between the two calls to DataContainerImpl.createRootNode(). First call happens during the @Inject phase and at that point, DataContainerImpl's config has not been set yet so, getting node numbers is called with usingMvcc=false. This leads to getChildrenDirect() being called on the root node and this call fails. See attached logs to compare deployment when TRACE is enabled versus deployment when DEBUG is enabled.
