Spring 3 classpath scanning fails on JBoss AS 6.0.0.M3 [SPR-7197]

[spring-projects-issues]

Marius Bogoevici opened SPR-7197 and commented

Context scanning fails in JBoss AS 6.0.0.M3 due to VFS issues. The VFS classes have moved from org.jboss.virtual to org.jboss.vfs. As well, a few methods have changed their names. Therefore, the fixes provided for #9793 need an update to match the current package structure.

I will attached a patch that abstracts the VFS2 and VFS3 code so that Spring 3 can detect the VFS version and run in either environments (JBoss AS 5 and JBoss AS 6).

An explanatory note about the issue: After deploying on JBoss AS 6.0.0.M3, applications that use CP scanning will fail with an error like:

04:48:24,881 ERROR [org.springframework.web.context.ContextLoader] Context initialization failed: java.lang.NoClassDefFoundError: org/jboss/virtual/VirtualFileVisitor

which indicates the package renaming that took place in the server (should be org/jboss/vfs/VirtualFileVisitor

Attached a patch for fixing the issue. Introduces an abstraction layer that detects the VFS version on the CP. As the operations are performed by reflection, it is not necessary to compile against the JBoss VFS jars anymore. The patch is produced by svn diff and has picked up some ipr changes as well. The latter can be discarded.

Thomas, any chance that you could have a look at this for 3.0.3 still? At least for an initial cut that works across JBoss AS 5 and 6?

Jürgen, Thomas,

Thanks for looking into this so quickly. If the fix could be done for 3.0.3 it would be awesome. Let me know if I can be of any help.

I've changed this issue to an improvement since it's not really Spring's fault that JBoss AS changed its VFS package - and we didn't have a chance know about it upfront (i.e. at 3.0 GA time). JBoss 6 simply wasn't fully supported before.

In any case, it would be great if we could provide a painless user experience on JBoss 6 for Spring 3.0.3 already. That said - I am concerned that the integration testing effort might not easily fit into the 3.0.3 timeframe anymore...

Committed the fix - tested it on JBoss 6 M3 and 5.1. Additional testing is welcome.

I'll consider this as finished, with just some smoke re-testing to be done from our side before the 3.0.3 release.

Would be great to have this tested in others' JBoss environments as well, of course...

Costin, Juergen,

I have tested tonight's trunk version of Spring 3 against JBoss AS 5.1 and 6(M3/trunk) and it everything looks fine.

Thanks for applying the patch!

Just for the benefit of replication, I have confirmed that this is no longer a problem. I had 3.0.1 and was getting this error, but when I upgraded the libraries to 3.0.5 the error went away.

Can I ask a simple question? How can I use this patch. I mean import into my current project.

I have an old project with spring framework 3.0.2 while it's hard to upgrade to a newer version.

Thanks a lot
