Hi, 

Eclipse Indigo 3.6 latest 2011/12/29
m2e latest
m2e-wtp latest
jBossTools latest

Maven project is jboss-sar packaging configured with jboss-packaging-maven-plugin.

Import Maven Project:

java.lang.NullPointerException
    at org.jboss.ide.eclipse.as.wtp.core.vcf.ExportedClassFolderReferenceResolver.canResolve(ExportedClassFolderReferenceResolver.java:36)
    at org.eclipse.wst.common.componentcore.resolvers.ReferenceResolverUtil.getResolver(ReferenceResolverUtil.java:43)

    at org.eclipse.core.internal.events.NotificationManager$1.run(NotificationManager.java:291)
...

Seems that "ReferencedComponent.getHandle()" returns null.

Project builds with mvn OK, project import doesn't complete with NPE above, in Eclipse Indigo, m2e and m2e-wtp, with jBoss Tools Maven integration.

Other projects in workspace (EAR, WAR, Dynamic Web Modules) import and build OK and work with m2e-wtp OK.

How can I resolve this?
