[jboss-jira] [JBoss JIRA] (JGRP-1550) 2.6.22.Final not running on 1.6 JVM

[MIchael Yates (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1550?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12739827#comment-12739827 ] 

MIchael Yates commented on JGRP-1550:
-------------------------------------

In fact the code I pull at that label contains the following

--
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <source>1.5</source>
    <target>1.5</target> 
    <excludes>
      <exclude>org/jgroups/util/JUnitXMLReporter.java</exclude>
      <exclude>org/jgroups/demos/**</exclude>
   </excludes>
 </configuration>
--

And therefor produces (after some additions to the pom) classes with 31 major version
hexdump -n20 ./org/jgroups/MembershipListener.class 
0000000 ca fe ba be 00 00 00 31 00 0d 07 00 0b 07 00 0c

Maybe when the build was done there was a partially edited version of the main pom checked out?

> 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 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?
