Subject [jira] [Created] (JAMES-1815) Crash when reading domainlist via JMX
Date Tue, 09 Aug 2016 09:35:21 GMT
Tobias Fleig created JAMES-1815:
-----------------------------------

             Summary: Crash when reading domainlist via JMX
                 Key: JAMES-1815
                 URL: https://issues.apache.org/jira/browse/JAMES-1815
             Project: James Server
          Issue Type: Bug
          Components: JMX
    Affects Versions: 3.0.0-beta5
            Reporter: Tobias Fleig


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.
