Where exactly is this "server lib" directory that you describe? If it's
one of the locations that gets loaded automatically, you should NOT be
loading anything in that location with the <lib> directive in
solrconfig.xml. That will result in the jar being loaded more than once.

This problem with a Java program can be caused by having the same jar
loaded more than once. The reason it happens is complex and has to do
with interactions between multiple Java classloaders.
The solution to these problems is to make sure that every required jar
is loaded, and that each of them is only loaded once.
