Also, the *only* related stuff in the boot.log now is:

[alrubinger@localhost Branch_5_x_BootstrapLegacyRemoval]$ cat build/output/jboss-5.1.0.GA/server/default/log/boot.log |grep "AbstractManagedObjectFactory"
18:49:38,064 DEBUG [AbstractManagedObjectFactory] Set ICF for: interface org.jboss.beans.metadata.spi.BeanMetaData, to: org.jboss.deployers.plugins.managed.BeanMetaDataICF@7fefa490
18:49:38,261 DEBUG [AbstractManagedObjectFactory] Set ICF for: class org.jboss.system.metadata.ServiceMetaData, to: org.jboss.system.deployers.managed.ServiceMetaDataICF@288e85b5

Hmm, changes I made to the ProfileServiceBootstrap are in changing the type of server used...what do you mean by "relies on the context injection of Bootstrap implementations"?
