Description

my typical use of Solr is something like this:

cd SOLR_HOME/example
cp -r solr /myProjectDir/solr_home
java -jar -Dsolr.solr.home=/myProjectDir/solr_home  start.jar

But in solr 4.5.0 this fails to start successfully. I get an error:

org.apache.solr.common.SolrException: Error loading class 'solr.clustering.ClusteringComponent'

The reason is because solr.clustering.enabled defaults to true now. I don't know why this might be the case.

you can get around it with

java -jar -Dsolr.solr.home=/myProjectDir/solr_home -Dsolr.clustering.enabled=false start.jar

SOLR-4708 is when this became an issue.
