> Reading the list of domains via JMX from:
> ObjectName: "org.apache.james:type=component,name=domainlist", Attribute "Domains"
> crashes with:
> java.lang.UnsupportedOperationException
> 	at com.google.common.collect.ImmutableCollection.add(ImmutableCollection.java:96)
> 	at org.apache.james.domainlist.lib.AbstractDomainList.getDomains(AbstractDomainList.java:131)
> 	at org.apache.james.domainlist.lib.DomainListManagement.getDomains(DomainListManagement.java:69)
> 	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
> Some subclasses (JPADomainList, HBaseDomainList, MemoryDomainList) return an ImmutableList
in getDomainListInternal(). This list is then modified by getDomains() in AbstractDomainList,
which causes the crash above.
> We will supply a patch/pull request.
