Thanks for the bug report and the test program.

This particular bug was fixed by Michael Koch in the Classpath CVS, and 
merged back into kaffe's CVS. But as I get from the follow up mail on 
the kaffe mailing list, you're still seing problems with NIO with the 
merged code. I'll check if there is some new NIO code to merge back ;)
