Using @SpringBean - NoSuchMethodError

[jweekend]

1.3betae3

With no @SpringBean annotation, I can get to the HomePage.
When I put it back in (to inject the DAO, see below), and the
ComponentInjector gets called to do it job, I get:
 
--- Error ---
WicketMessage: Can't instantiate page using constructor public
com.sjw.HomePage(org.apache.wicket.PageParameters) and argument

Root cause:

java.lang.NoSuchMethodError:
org.apache.wicket.util.lang.Classes.isPrimitive(Ljava/lang/Class;)Z

with the following simple set up:
