---------------------------------
Summary: add support for proxying protected methods in
NormalScopedProxyFactory
Key: OWB-768
URL: https://issues.apache.org/jira/browse/OWB-768
Project: OpenWebBeans
Issue Type: Bug
Components: Core
Affects Versions: 1.2.0
Reporter: Mark Struberg
Assignee: Mark Struberg
Fix For: 1.2.0
Our Normalscoping proxies now roughly look like the following. For a
public class User {
public String getName() { return "Hans"; }
}
we create a dynamic subclass with ASM:
public class User$OwbNormalscopeProxy extends User {
private Provider<User> owbContextualInstanceProvider; // will be set by the
proxy factory
public String getName() {
return owbContextualInstanceProvider.get().getName();
}
}
The problem arises when getName() is not public but protected. In this case
various access restrictions for protected variables kick in. For more details
please read Java Langspec 3.0 ยง6.6.2 [1]. Especially take note of the second
sample in 6.6.2.2.
There are additional restrictions listed in the JVM spec becaues 2 packages
technically are only counted as equals if they get loaded by the same
ClassLoader.
For those reasons I currently disabled proxying of protected methods for now.
The long time solution might be to use reflection to invoke the proxied
methods. I will introduce a static method in the NormalScopeProxyFactory which
will contain all the necessary handling and can easily be used concurrently by
all generated proxies.
