Description

Various items are missing in the Java client:

• finish synchronized Scanner API
• double check that APIs are nice and exportable (eg using builders rather than lots of arguments, so we can add new ones compatibly)
• figure out our shading or classloaders so we don't get bit by dependency disasters
