1) somebody else is also putting some BMD under BMD.class.getName attachment -- hence overlapping/'overridding' our PU

This is not the case, as PUDeployer is already working on component,
hence I would be surprised if some other deployer would work on the same component + overridding BMD attachment.

Weird ... since it should *not* be allowed to go to Create state
if @Inject dependency wasn't satisfied ...

I know what is the issue. ;-)

It's this change:
- https://jira.jboss.org/jira/browse/JBDEPLOY-118

The problem there is that you're by-passing BMDFVisitor
that adds CLASS level scope to DUs Scope:

 protected DeploymentUnit addComponent(DeploymentUnit unit, BeanMetaData attachment)
 {
 DeploymentUnit component = super.addComponent(unit, attachment);
 String className = attachment.getBean();
 if (className != null)
 {
 Object qualifier;
 if (attachment.getClassLoader() == null)
 {
 ClassLoader cl = unit.getClassLoader();
 try
 {
 qualifier = cl.loadClass(className);
 }
 catch (Exception e)
 {
 throw new IllegalArgumentException("Exception loading class for ScopeKey addition.", e);
 }
 }
 else
 {
 qualifier = className;
 }
 component.getScope().addScope(CommonLevels.CLASS, qualifier);
 }

 return component;
 }

So, the solution is that you stop hacking around components. ;-)
Component deployer shouldn't create new attachments, else similar issues can pop up.

Perhaps do this:

 DeploymentUnit parent = unit.getParent();
 if (parent == null)
 throw new IllegalArgumentException("Should not be null as this unit should be component.");

 parent.addAttachment(BeanMetaData.class.getName() + "." + name, builder.getBeanMetaData(), BeanMetaData.class);

As components are auto(magically) registered by DeploymentContext.

I changed how we name PUMD component.
