This is indeed a limitation of the Java uploader. I agree that it would be a worthwhile feature to add. I've added it to our Mantis here:

This is an inconvenient bug in pydas that we haven't gotten around to fixing as of yet. A workaround would be to create a new API key for you user on the Api tab of your user profile. Here's how:

1) Log in.
2) Hover over your name in the upper right and select "My Account"
3) Select the Api tab.
4) Generate a new API key with a longer default expiration time.
6) Authenticate with pydas using the new API key.

This is definitely a bug. Could you send the script and hierarchy for testing. Also, for completeness, could you ensure that you are running on the latest version of pydas?

This bug is being worked on by a core developer right now. :)
