I have a recent build of solr (4.0.0.2011.02.25.13.06.24). I am seeing this error when making a request (with fq's), right at the point where the eviction count goes from 0 up:
severe: java.lang.classcastexception: [ljava.lang.object; cannot be cast to [lorg.apache.solr.common.util.concurrentlrucache$cacheentry If you then make another request, Solr response with the expected result. Is this a bug? Has anyone seen this before? Any tips/help/feedback/questions would be much appreciated! Thanks, Matt
