I think there must be incorrect versions of jars in unexpected places,
or you're not compiling against the same version of Solr jars as the
version you're running, or perhaps theSolr install you've got has old
versions of jars hanging around, either from an old extracted .war file
or elsewhere on the classpath.
Here's an old thread:

Thanks,
