I was having a problem in a 4.x version of Solr and wanted to check 5.2.1 to see if it still had the same problem, so I copied my fieldType into a 5.2.1 example schema. My fieldType uses some ICU analysis classes, so I also put the contrib jars into server/solr/lib.
I ran into a problem similar to SOLR-4852. https://issues.apache.org/jira/browse/SOLR-4852 The Solr log shows the icu jars being loaded twice, and i got a class not found exception for the ICU classes. If I change the schema from the "short" factory class name (solr.ICUTokenizerFactory) to the full class name (org.apache.lucene.analysis.icu.segmentation.ICUTokenizerFactory), then it works. I'm guessing that the root of the problem is the fact that the jars are loaded twice ... but I cannot see any reason for them to be loaded twice. They are not mentioned in any <lib> directives in solrconfig.xml, and there is no sharedLib declaration in solr.xml. The core that I created was using the techproducts sample config. Should I open an issue for this problem? I canprovide a very clear step-by-step minimal process for showing the problem with a stock 5.2.1 download. Thanks, Shawn
