http://community.jboss.org/message/539484#539484 -------------------------------------------------------------- Having revisited how the classpools are set up ( http://community.jboss.org/thread/151095 http://community.jboss.org/thread/151095) which became apparent after looking into ( http://community.jboss.org/message/538568#538568 http://community.jboss.org/message/538568#538568) and fixed the problems to do with generating accessors for classes loaded by a parent of the jboss-reflect classloader I now end up with the following

The problem here is for parameterized type infos. We currently use the type info of the raw type for the whole parameterized type which will not work for things like java.util.Set<org.jboss.beans.metadata.spi.AnnotationMetaData> since the raw type (Set) comes from the system classpath and thus cannot see the actual type argument classes (AnnotationMetaData is further down in the classloader hierarchy). Parameterized type infos will need to be cached differently, I'll look at how these are handled in plain java across different classloaders. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/539484#539484] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
