Davenport needs JRE 5

Hello,
I wanted to report an issue I had with davenport 0.9.11 (I assume the latest version ?). When trying to access using a webdav client (cadaver, office 2 hd (ipad)) I would get this exception stack:
23:29:03.907 WARN!!

After a bit of googling, trials and (many) errors, I found out the problem comes from the version of java I was using. I searched for the 1st line of the exception stack (google) and found similar issues. The answers mentioned an incompatibility issue when running on jre 6 (the one coming with ubuntu "natty" by default). I installed an old jre 1.5.0_22. With this davenport seems to be working all right.
Maybe this should be added to the troubleshouting section ?
I had trouble finding old versions of JRE / JDK for linux (I am running davenport on ubuntu natty). Do you have any plan to upgrade so that davenport can work with newer JREs ?
