Greetings!

Thank you for the report Jesse! Did you run into a similar issue in 5.1 by
any chance?

I've created a github issue to make sure we don't lose track of it:

https://github.com/Unidata/netcdf-java/issues/140

If you have a github account and don't mind, we can take the conversation
over there. Otherwise, here is good :-)

Cheers!

Sean
