Update is hung up

Trying to run an update using the V2 jar. It's hung up with the Applying Update bar about halfway through and the Setting Up bar about a third of the way through. I get the following Java console error followed by a timeout error and then repeating null pointers:
null device error
java.lang.ArrayIndexOutOfBoundsException
at java.lang.System.arraycopy(Native Method)
at com.ross_tech.hexnetconfig.m.c(Unknown Source)
at com.ross_tech.hexnetconfig.m.f(Unknown Source)
at com.ross_tech.hexnetconfig.ad.run(Unknown Source)
at java.lang.Thread.run(Thread.java:745)

I currently still have it plugged in, please advise if I should unplug and retry.

Edit: I'm using Open-JDK-7

Yep, reboot the HEX-NET.

Thanks. The firmware worked, can't get it to do the chassis update though, either with the tool or through the html interface.

What versions of stuff are currently in there?

Are you running this on linux? If so, try running the config as root.

Running the utility isn't a problem, I've tried it as root from a terminal and through opening it from a root explorer. However, the download I did yesterday was V2.005. Is there a later version somewhere? The firmware now shows as up-to-date (I don't recall exactly which version it is) but the chassis update fails. Everything is working again now.

Edit: Nevermind, I found .007.
