No this is not something XBean has addressed. In the future we are
going to lean on maven artifact for dependency resolution, and I
think they have a way to have artifacts with multiple jar files each
of which is targeted to a specific jvm version.

In HEAD now and 1.1 when it comes out there will be a message
indicating if the JDK level your using isn't supported so people
will at least have a heads up. Given JDK 6 is on the horizon this
sounds like an additional dependency. Dain, does XBean have this
as one of the attributes so a check can be made? I'd hate to see
multiple CARs (one for each JVM level).

Based on the number of problems people have encountered trying to use
the 1.5 JRE I'd say this is a very prudent suggestion. I personally
like the second approach best because IIUC it doesn't affect the
schema. It might also be neat for Geronimo to have a stock GBean
that
compares the properties it gets passed against the runtime env and
provides a clear error message and/or fails to start if they don't
match. Applications/components with specific runtime reqs could
optionally reference it in their plans. Just a thought...

It sounds like we could run into this issue in the future where a
configuration (possibly provided by a third party) has a minimum JDK
requirement.
Would it make sense to have the minimum JDK requirements in the
plan XML
so we can gracefully skip loading configurations when the hosting VM
does not meet the requirements?
Another approach could be to specify configuration activation
criteria
(e.g. like Maven 2's activation element in the pom) so one could
provide
an assembly with some configurations for specific JDK levels or
possibly
for specific operating systems (e.g. if you have configurations
that use
JNI to provides access to particular O/S features) where the
configurations only get started if they are running in the
appropriate
environment.
Not high priority, but thought it might be worth discussing for
the future..
