[kaffe] AbstractSelector.java:cancelledKeys() - small patch for Freenet

[Dalibor Topic]

Hi david,

Thanks again for the patch.

I merged in more updates to the NIO code from GNU Classpath made by 
Michael Koch, so you patch doesn't apply anymore. Could you check out 
kaffe from CVS and try again, to see if it fixes the problem?

cheers,
