To clarify,

Having the options duplicated wouldn't really be a problem, except
when javaagent is duped I get three agents started.
To demonstrate I made this:
https://github.com/tims/HelloWorldAgent
It prints hello world once per second, but I'm getting 3 lines printed
every second.

I have made a jira for this here:
https://issues.apache.org/jira/browse/HBASE-3561
