[jira] Commented: (AMQ-1185) ActiveMQ 4.1 has crept in some Java 5 APIs, which prevent it from being used on Java 1.4 JVMs

Jason Dillon commented on AMQ-1185:
-----------------------------------

Ugh... appears there are a bunch of test failures with the above... though very hard to find them due to all of the output from the tests :-(

But they are failing with things like:

Which shows there is more Java 5 stuff lingering around... perhaps in some other dependency?

> 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.
