Fully disable Weld JSF integration in Wildfly 8.2

Question

I'm in the process of migrating a Seam 2.3 web application to EE7. Currently the application runs on Wildfly 8.2 (with Bill of Materials version of all dependencies) and runs fine, except for a performance issue: pages take minutes to load, or never do.

It appears Weld/CDI related. WeldApplication is added somewhere to the faces application chain, which causes constant failed attempts resolving BeanManager, plus occasionally some thread locking issues.

I've tried stripping the weld module out of wildfly, or run with weld module enabled but set to require-bean-descriptor. My project contains no beans.xml.

is it possible to prevent WeldApplication from being added to the faces application chain?. At least until I'm at a stage in the migration to get rid of Seam.

Workaround: My current work around is a bit of a hack but seems to do the trick. I've added my own ApplicationFactory to faces-config.xml, that basically circumvents the WeldApplication.

@Override
public Application getApplication() {
    return new MyApplication( delegate.getWrapped().getApplication() );
}

Edit #1: Stack trace with performance issue hotspot to give some context.

Answer 1

Im not sure if this would work for Wildfly but I am using the following snippet in the <deployment> block in jboss-deployment-structure.xml to disable Weld in JBoss AS 7.2.0
