I filed SOLR-4852. Resource loading seems to be a black art with Solr!
The only jars you need for the ICU analysis components are
lucene-analyzers-icu-4.3.1.jar and icu4j-49.1.jar, possibly with
different version numbers in the names.
Are you defining solr.solr.home explicitly? I'm just wondering if maybe
${solr.solr.home}/lib isn't where you think it is, or whether maybe
there's another copy of the jars somewhere on the classpath. The log
should show which jars are loaded ... do you see either of the above
jars loaded more than once? If you do, that seems to be the trigger for
the problem. All but one copy needs to be removed.
If the jars exist in the extracted WAR (the WEB-INF location you
mentioned), everything seems to work, but the problem with this is that
when you replace the .war file, your changes to the extracted war will
either be outdated or possibly will get removed. It is good practice to
entirely remove the extracted .war contents when upgrading Solr.
Thanks,
