-----------------------------------

             Summary: 2.6.22.Final not running on 1.6 JVM
                 Key: JGRP-1550
                 URL: https://issues.jboss.org/browse/JGRP-1550
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.6.21
         Environment: JVM 1.6
            Reporter: MIchael Yates
            Assignee: Bela Ban


2.6.22 has been built using JDK 7

#A dump from a 2.6.21 class
hexdump -n20 ./org/jgroups/MembershipListener.class 
0000000 ca fe ba be 00 00 00 32 00 0d 07 00 0b 07 00 0c

#A dump from a 2.6.22 class
hexdump -n20 ./org/jgroups/MembershipListener.class 
0000000 ca fe ba be 00 00 00 33 00 0d 07 00 0b 07 00 0c

Note the 8th octet has changed form 32 to 33. ie from JVM6 to JVM7

I suspect this is an oversight when 2.6.22 was built. Maybe -source and -target parameters forgotten on the build?
