Description

Currently the JDBCStream uses Class.forName() to load the driver class. This should be improved to try to use the classloader from runtimeLib and the blob store API like SOLR-10087. It may be possible to do something like Class.forName(driverClassName, true, core.getMemClassLoader()) just need to figure out how to get a reference to the core.

The relevant code is here:
