Description

A few bits of Java 5 API has made it into the AMQ 4.1 branch, which prevent 4.1 from being used on Java 1.4 JVMS.

Apache Geronimo v1.2 needs AMQ 4.1 running on Java 1.4.

So far I don't see anything major which prevents AMQ 4.1 from being compiled with Java 1.4... only a few minor changes to keep compatibility. The alternative is of course to use the retrotranslator-maven-plugin to generate 1.4 compatible jars for each module (the new retrotranslator:translate-project makes this very easy to use, includes attaching jdk14 artifacts).

But IMO, that would just add more complexity for AMQ 4.1 when only a few simple changes will allow the it to be native 1.4... though you folks might consider using retrotranslator:translate-project for trunk to create 1.4 compatible jars for the new AMQ (> 4.1.x) bits.
