Any free, open-source manager-side SNMP Java libraries besides SNMP4J?

I have the SNMP4J distribution, which looks at first glance to be capable and current. For good, healthy due diligence on my client's behalf, though, I'd just as soon see one or two more such libraries.

Anybody know of any other SNMP libraries written in Java? This would be for the manager side; t开发者_开发知识库he agent side is in good shape.

There are a number of SNMP java stacks. Some quick googling or searching on FreshMeat will show you quite a few.
