[cdi-dev] [JBoss JIRA] (CDI-362) No-interface view EJB proxying rules are less strict than CDI, leading to odd error reporting

[Pete Muir (JIRA)]

    [ https://issues.jboss.org/browse/CDI-362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12765057#comment-12765057 ] 

Pete Muir commented on CDI-362:
-------------------------------

CDI descries what can't be proxied:

{quote}

The container uses proxies to provide certain functionality. Certain legal bean types cannot be proxied by the container:

* classes which don’t have a non-private constructor with no parameters,
* classes which are declared final,
* classes which have non-static, final methods with public, protected or default visibility,
* primitive types,
* and array types.

{quote}

and then goes on to say when and how these rules are applied:

{quote}

A bean type must be proxyable if an injection point resolves to a bean:

* that requires a client proxy, or
* that has an associated decorator, or
* that has a bound interceptor.

Otherwise, the container automatically detects the problem, and treats it as a deployment problem.

{quote}

To answer your specific questions:

1) Yes - CDI never looks at private methods when considering whether a type is proxyable.
2) non-private methods cannot be declared final in order to be proxied
