Please find attached a small test program which reproduces the following crash under Kaffe 1.1.2:
/usr/local/kaffe/bin/java -classpath build telnet.TelnetServer waiting for connections on 1234 java.lang.NullPointerException at gnu.java.nio.SelectorImpl.deregisterCancelledKeys (SelectorImpl.java:234) at gnu.java.nio.SelectorImpl.select (SelectorImpl.java:146) at gnu.java.nio.SelectorImpl.select (SelectorImpl.java:92) at telnet.TelnetServer.serve (TelnetServer.java:93) at telnet.TelnetServer.main (TelnetServer.java:22)
I have looked quickly on the problem, and it seems SelectorImpl.deregisterCancelledKeys() calls cancelledKeys(), which is inherited as "returning null" from AbstractSelector:
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 ;)
cheers, dal
