Hi all,

I'm trying the M5 release of virgo, but when deploying my WAR file I get an error concerning packageImports of LF4J:

[2011-06-06 11:55:21.467][2011-06-06 11:55:20.209] INFO  start-signalling-2           org.eclipse.virgo.medic.eventlog.default                         WE0000I Starting web bun

ernel.userregion.internal.importexpansion.AbstractTrackedPackageImports.convertImportedPackageListToMap(AbstractTrackedPackageImports.java:323)

But as I'm deploying a war file I'm not even managing the manifest files...they are still the empty defaults.

Or is the LF4J bundle I might be using the source of the problem perhaps?

If so, would it be possbile to solve this by removing the package from the project, and use a dependency on the Virgo bundle for LF4J instead?

Thanks a lot in advance,

Jochen

It seems like the WAR file might contain a manifest with an import for a SLF4J package, but it's hard to tell.

If you can cut down the WAR file to a bare minimum necessary to reproduce the problem, you may discover the problem in the process. But if not, you could then open a bug and attach the WAR file for us to try.
