> 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.
