Ahh, I had a jboss-classloading.xml left over from the earlier experiment. It does not have a requirements bit at the moment, but it does have <classloading xmlns="urn:jboss:classloading:1.0" export-all="NON_EMPTY"> which seems to override the default behaviour even though it's missing any explicit import-all clause. Changing to <classloading xmlns="urn:jboss:classloading:1.0" export-all="NON_EMPTY" import-all="true"> makes it behave the way I want. Thanks for the help.
