I am very excited to try it out. When trying to deploy my app (that works okay on JBoss 5.1.0.GA), I get the following exception: 13:43:55,421 ERROR [AbstractKernelController] Error installing to PostClassLoader:

The method that is being 'scanned and visited' and causing the problem is my method: *private Pair<Member, String> importMember( String memberRow, Company importCompany, Plan importPlan, String stylesheet, int fileNumber, String dataDate )* My class Pair is defined as: *public class Pair<L, R>* The problem is that in *ParameterizedTypeImpl.validateConstructorArguments(ParameterizedTypeImpl.java:42)* it is trying to marry the actualTypeArguments <Member, String> (which it has parsed from the return type of the method) with the class Pair's *Class.getTypeParameters()* Now here is the mystery: *Class.getTypeParameters()* is returning an empty Array, rather than <L, R>. If I try Class.forName at this point I get an Exception, which leads me to believe that the Pair class is being constructed artificially by the JBoss MC scanner and GenericAnnotationVisitor? Possibly it is being constructed incorrectly, without generic type arguments? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/577806#577806] Start a new discussion in JBoss Microcontainer at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2114]
