Shawn Heisey commented on SOLR-4852:
------------------------------------
There may be some confusion about what's going on with this issue.
This issue affects 4.3 and later. Summary: If you are putting jars in
solrhome/lib then you must remove any sharedLib setting that points at this
directory, either with "lib" or an explicit path. Also, you cannot put some
jars in solrhome/lib and others in a location specified by sharedLib - they
must all be in the same location.
The same config won't work on 4.2.1 and earlier if you are putting jars in
solrhome/lib. The sharedLib attribute must exist and point at that location,
or you will see that the classloader loads the jars, but the classes in those
jars are not found when the config or schema tries to use them. This part is
something I learned today while trying to work with the older version.
> 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.
