[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=12739813#comment-12739813 ] 

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

I am not sure if it helps track down what went wrong but there are a few other anomalies with this release as well. 
- no release notes available here: https://issues.jboss.org/secure/ConfigureReleaseNote.jspa?projectId=10053
- 21 is labelled 2.6.21.FINAL whilst 22 is labelled 2.6.22.Final. Note the difference in capitalisation. 

Certainly I am not saying that these things are the cause. Just noticing that there seem to be other differences in this 2.6.22 release vs the 2.6.21 release.

I am yet to try your suggestion of building my own version of the jar - but feel fairly comfortable it will be a suitable workaround for our situation.

> 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?
