>                 Key: SOLR-7771
>                 URL: https://issues.apache.org/jira/browse/SOLR-7771
>             Project: Solr
>          Issue Type: Bug
>    Affects Versions: 5.2.1
>         Environment: C:\Users\elyograg\Downloads\solr-5.2.1>java -version
> java version "1.8.0_45"
> Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
> Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
>            Reporter: Shawn Heisey

> Jars placed in SOLR_HOME/lib seem to be loaded twice, which causes problems trying to
use solr.XXXXXX class names in schema.xml.
> If the full class name is used, it works.
> Steps to recreate on an extracted Solr 5.2.1 download.  This was done on Windows, so
I used backslashes as path separators:
> {noformat}
> bin\solr start
> bin\solr create -c foo -d sample_techproducts_configs
> bin\solr stop -all
> {noformat}
> Add the following to server\foo\conf\schema.xml, just before the </schema> end
tag:
> {noformat}
>     <fieldType name="icu_test" class="solr.TextField">
>       <analyzer> 
>         <tokenizer class="solr.ICUTokenizerFactory"/>
>       </analyzer>
>     </fieldType>
> {noformat}
> Create a new directory -- server\solr\lib.
> Copy icu4j-54.1.jar and lucene-analyzers-icu-5.2.1.jar from contrib\analysis-extras to
server\solr\lib.
> {noformat}
> bin\solr start
> {noformat}
> Note an exception in the logging tab:
> java.lang.NoClassDefFoundError: org/apache/lucene/analysis/icu/segmentation/ICUTokenizer
> At this point, if the class name is changed from solr.ICUTokenizerFactory to org.apache.lucene.analysis.icu.segmentation.ICUTokenizerFactory
and solr is stopped and started, then everything is OK.
