[jcifs] NtlmHttpFilter java.lang.ExceptionInInitializerError & java.lang.NoClassDefFoundError

[Michael B Allen]

JCIFS does not work if the objects it puts into the session are
serialized. This can happen in a cluster environment or when restarting
a container.

The only solution is to somehow disabled session serialization for
the filter.

There is a fundamental problem with trying to use a stateful
authentication protocol (NTLM) over a stateless transport (HTTP).
