Interesting because I am able to reproduce your error by passing <jar1>::<jar2> to -Dpig.additional.jar. Setting PIG_CLASSPATH itself with :: seems fine, but passing it to -Dpig.additional.jar is not.
If you still run into a failure, can you double-check whether you're seeing the same error or a different one? You shouldn't see the same error.
