[jboss-jira] [JBoss JIRA] Commented: (JBDEPLOY-270) Intermittent failure of undeploy

Intermittent failure of undeploy -------------------------------- Key: JBDEPLOY-270 URL: https://issues.jboss.org/browse/JBDEPLOY-270 Project: JBoss Deployers Issue Type: Bug Components: deployer Affects Versions: JBDEPLOY-2.0.10.GA Reporter: Dennis Reed Attachments: JBDEPLOY-270-jboss-beans.xml When components are deployed, they are assigned names with a number appended based on the order it was processed. For example "jboss.deployment:id="dennis$defaultEvictionRegionConfig#1",type=Component" The number is assigned in (line #'s are from EAP 5.0): at org.jboss.beans.metadata.plugins.AbstractBeanMetaData.setName(AbstractBeanMetaData.java:360) at org.jboss.beans.metadata.plugins.NestedBeanHandler.checkForNestedBeans(NestedBeanHandler.java:77) at org.jboss.beans.metadata.plugins.AbstractBeanMetaData.getBeans(AbstractBeanMetaData.java:202) at org.jboss.kernel.plugins.deployment.AbstractKernelDeployment.getBeans(AbstractKernelDeployment.java:233) at org.jboss.deployers.vfs.deployer.kernel.KernelDeploymentDeployer$KernelDeploymentVisitor.getBeans(KernelDeploymentDeployer.java:63) at org.jboss.deployers.vfs.deployer.kernel.KernelDeploymentDeployer$KernelDeploymentVisitor.getBeans(KernelDeploymentDeployer.java:54) at org.jboss.deployers.vfs.deployer.kernel.BeanMetaDataFactoryVisitor.deploy(BeanMetaDataFactoryVisitor.java:118) However, the beans are *not* processed in the same order every time. And they are processed separately during deployment and undeployment. This means that "myBean#1" may get deployed, but "myBean#2" is undeployed (leaving "myBean#1" still deployed). Subsequent deployments will fail with errors: 17:34:30,630 WARN [AbstractDeploymentContext] Unable to register deployment mbean dennis$defaultEvictionRegionConfig#1 javax.management.InstanceAlreadyExistsException: jboss.deployment:id="dennis$defaultEvictionRegionConfig#1",type=Component already registered. The root cause appears to be that the XML descriptor is read with jboss-xb using a Set (unordered), but then this code has a dependency on the order being consistent between deploy and undeploy.
