ManagedStopFilterFactory not accepting ignoreCase

[Mike Thomsen]

We're running Solr 4.10.4 and getting this...

Caused by: java.lang.IllegalArgumentException: Unknown parameters:
{ignoreCase=true}
        at
org.apache.solr.rest.schema.analysis.BaseManagedTokenFilterFactory.<init>(BaseManagedTokenFilterFactory.java:46)
        at
org.apache.solr.rest.schema.analysis.ManagedStopFilterFactory.<init>(ManagedStopFilterFactory.java:47)

This is the filter definition I used:

<filter class="solr.ManagedStopFilterFactory"
                      ignoreCase="true"
                      managed="english"/>

Any ideas?

Thanks,

Mike
