duplicated spring bundles [message #911737]

I am using virgo 3.0.1 and I am having problems with Uses violation, it happens because virgo starts 2 identical spring bundles.
One in lib/kernel:

Bundle Location 	file:lib/kernel/org.springframework.asm-3.0.5.RELEASE.jar

And the other in repository/ext:

Bundle Location 	org.eclipse.virgo.region.user@file:/C:/virgo-web-server/repository/ext/org.springframework.asm-3.0.5.RELEASE.jar.

If I try to remove on of the bundles virgo doesnt start.

Why does virgo need these duplicated bundles ?

Hi,

This is a trade off between duplication and performance. The lib directory contains the bundles that Virgo needs to start, Equinox can just launch all the bundles in the folder quickly without worrying about repository indexing, deployer pipelines and so on. If we don't use the lib directory approach then starting Virgo gets slower.

Hope that explains it, it would be nice to get the performance without duplicating bundles but we couldn't figure out how to do so when designing that part of the system

but this duplication is causing me conflicts, how can I tell a bundle ( not one of mine rather a third party ) which of the duplicated bundles to use ?
