[jira] Created: (OWB-185) Managed beans with non-default
constructors lead to InstantiationException when creating the proxy
Managed beans with non-default constructors lead to InstantiationException when creating the proxy
--------------------------------------------------------------------------------------------------
Key: OWB-185
URL: https://issues.apache.org/jira/browse/OWB-185
Project: OpenWebBeans
Issue Type: Bug
Components: Injection and Lookup
Affects Versions: M3
Reporter: Joe Bergmark
Assignee: Gurkan Erdogdu
While working on OWB-151 I ran into a problem with the way proxies are created for beans with non-default injected constructors. For example, you could look at
org.apache.webbeans.newtests.interceptors.lifecycle.LifecycleBean and give it a normal scope:
@RequestScoped
@LifecycleBinding
@Named("org.apache.webbeans.newtests.interceptors.lifecycle.LifecycleBean")
public class LifecycleBean
{
public static String CONSTRUCTOR_INJECTED = null;
@Inject
public LifecycleBean(@New String string)
{
CONSTRUCTOR_INJECTED = string;
}
public void touch(){}
}
Leads to the following exception (the stack trace is off slightly due to some refactoring I have done but the error should be the same):

Re: [jira] Created: (OWB-185) Managed beans with non-default
constructors lead to InstantiationException when creating the proxy
Posted by Joseph Bergmark <be...@gmail.com>.
I saw that 3.1.1 says that managed beans need to either have a default
constructor or have a constructor annotated @Inject, but I missed 5.4.1 with
the confusing double negative sentence that says that client proxies are
only valid for beans that "don't have a non-private constructor with no
parameters."
Thanks for the pointer!
Sincerely,
Joe

Re: [jira] Created: (OWB-185) Managed beans with non-default
constructors lead to InstantiationException when creating the proxy
Posted by Gurkan Erdogdu <cg...@gmail.com>.
If a bean is normal scoped, it must satisfy conditions at 5.4.1. Mean that
it has to default constructor.
I think that I was checked this situation in our impl. in
WebBeansUtil#checkUnproxiableApiType.
We have to look where this method is called.

[jira] Closed: (OWB-185) Managed beans with non-default
constructors lead to InstantiationException when creating the proxy
Posted by "Gurkan Erdogdu (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/OWB-185?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gurkan Erdogdu closed OWB-185.
------------------------------
Resolution: Fixed
Fix Version/s: M4
Look at chapter 5.4.1. Normal scoped beans must have default public constructor.
