> We have a custom snitch that works in 1.1, but the same does not work in 1.2 . It throws a ConfigurationException:
> {panel}
> ERROR 11:39:37,936 Fatal configuration error
> org.apache.cassandra.exceptions.ConfigurationException: Unable to find snitch class 'com.apigee.cassandra.OldEC2Snitch'

> However the above exception does not help us understand what's wrong (jar is in the classpath and readable). I've to add the root clause to the ConfigurationException to see the real problem:
