There are a couple bad characters (not UTF-8 compatible) on line 1184 of the org.lwjgl.openal.AL10.java class.
This causes me to have to replace them and then recompile it every time I update to the latest release (this has been this way for a few releases).
The line reads.
* The Unqueue command removes a number of buffers entries that have nished
The $@#@nished should be 'finished'... after removing the bad characters.
Cheers
thx, fixed in trunk
