> During TCP_NIO, I used to ignore exceptions thrown while closing connections at shutdown time.  I changed this for the 2.4 release, however, there seems to be a Java bug that Sun just fixed in Mustang build 89.  I verified that the Sun fix works by downloading jdk-6-rc-bin-b89-linux-i586-22_jun_2006.bin from http://download.java.net/jdk6/binaries/ and running the org.jgroups.tests.perf.Test.  I asked my support contact at Sun if they could also fix this bug in the Java 5 release, I'll update this bug when I hear the answer.
> I created this Jira to track the issue since others will likely see the same problem.  When Sun reports back their plans for a Java5 fix, I'll update this Jira.  The Sun bug id is supposed to be 6445262 but I cannot seem to find that on the Java bug parade (perhaps its marked private.)
> Run the attached script files to recreate.
> The stack trace below shows that the unexpected error occurs when we attempt to close the channel (socket connection):
> SEVERE: error closing socket connection
> java.io.IOException: Invalid argument
