Weird Error on Map Editor

[Pasokon]

Hello all,

I just downloaded the Map Editor (Java/Crossplatform) onto my Macbook. I
tried opening the Map Editor, but I get the following error:


You can't open the application "Wyvern
Map Editor" because it requires a version
of Java that is not available.

This application requires a "1.5.0_16" version of Java.
The available Java version "1.5" may be able to open
this application, but it may not work correctly.


However, when I check my version of Java, I get this:


eight-six:wyvern crosario$ java -version
java version "1.5.0_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b06-284)
Java HotSpot(TM) Client VM (build 1.5.0_16-133, mixed mode, sharing)


Anyone got any ideas how to fix this?
