From José Pinto (JIRA) <j...@apache.org>
Subject [jira] Commented: (IO-101) The method EndianUtils.writeSwappedDouble() and EndianUtils.readSwappedDouble() do not match!
Date Tue, 05 Dec 2006 11:11:22 GMT
    [ http://issues.apache.org/jira/browse/IO-101?page=comments#action_12455586 ] 
            
José Pinto commented on IO-101:
-------------------------------

I tried using the java.nio Buffer for the same purpose and it worked as expected. Maybe we
should look for differences in the code.
