Shawn Heisey commented on SOLR-6188:
------------------------------------
On 4.2.1, 4.3.0, 4.6.1, 4.7.2, and 4.9.1 (the only 4.x versions I have tested),
the workaround I mentioned in SOLR-4852 (putting all jars in solr_home/lib)
works with the "solr." prefix on ICU analysis components. On 5.2.1, it
doesn't, and full class names are required. All other typical classes are
working with the "solr." prefix except the ICU components.
