Issue Type: Bug Bug

Description:

I have a chain of decorators for a managed bean.

If they are enabled, the container tries to proxy the managed bean, although it uses the default @Dependent scope. When creating the proxy, it ignores the injected constructor with parameters and tries to use the default constructor with no parameters instead. As a result, this fails with an InstantiationException:

If I disable the chain of decorators, the example works as designed.

I will attach a ZIP file with the sample code.

I assess this as a critical bug because I don't want to rely on private field injection.
