This fails for no reason. By the way why does this load non - jar hidden .DS
file :
4.8.1/example/solr/collection1/lib/.DS_Store' to classloader
> If sharedLib is set to lib, classloader fails to find classes in lib

> I have some jars in the lib directory under solr.solr.home - DIH, ICU, and
> MySQL. If I set sharedLib in solr.xml to "lib" then the ICUTokenizer class
> is not found, even though the jar is loaded (twice) during Solr startup. If
> I set sharedLib to another location that doesn't exist, the jars are only
> loaded once and there is no problem.
> I'm using the old-style solr.xml on branch_4x revision 1485566.
