Please read http://uima.apache.org/d/uimaj-2.4.0/references.html#ugr.ref.xmi.array_and_list_features. This explains details of this and why it might be important (or not) in your application.
I think that by changing the setting of "multipleReferencesAllowed" you can tell the XMI serializer to serialize arrays in a manner which respect object identity. Finding out which array is exhibiting this would take patching the XMI serializer code which issues the warning. If you do a patch and attach it to a Jira issue ( https://issues.apache.org/jira/browse/UIMA ), we'll take a look at incorporating an impovement to the warning message being produced. -Marshall On 6/19/2013 4:14 PM, John David Osborne (Campus) wrote: > Does anybody know what the underlying reason that this WARNING is generated? > > WARNING: Warning: multiple references to an array.
