> With the introduction of a proper accumulo-test jar, this class moved out of server, but the libjars value was never updated in the merge and subsequently broke verify.
> The method is inlined in 1.6, so 1.6+ isn't broken. It appears that the merge up from 1.4 to 1.5 wasn't performed properly which introduced this in the first place. I'm not confident 1.4 isn't broken too, but since it's EOL, I'm not going to bother to investigate there.
