Servlet constructor injection fails on JBoss AS6.x

[larse]

I'm trying to inject a simple managed bean into my servlet using constructor injection with no luck.
I can inject the bean using field injection but constuctor injection fails with the stacktrace below.
I've tried jboss 6.0 and the latest 6.1 SNAPSHOT and get the same error. This works on glassfish 3.1.

Weld bug?

TomcatInjectionContainer doesn't delegate new servlet instance instantiation to Weld,
it only uses servletClass::newInstance.

• http://anonsvn.jboss.org/repos/jbossas/trunk/tomcat/src/main/java/org/jboss/web/tomcat/service/TomcatInjectionContainer.java

But if you use setters it would still work for you,
as the setter configuration code will be invoked before any servlet method (init, service, ...).
