[weld-issues] [JBoss JIRA] Resolved: (WELD-737) Proxy instantiation fails with IllegalAccessError for Beans with package private constructor

[Stuart Douglas (JIRA)]

Stuart Douglas resolved WELD-737.
---------------------------------

    Resolution: Rejected


After some more discussion we have decided that we are not going to replace the javassist proxy classes with weld ones. Replacing the javassist classes would only move the problem from 'javassist must be accessible' to 'replacement classes must be accessible'.

As I understand it the javassist classes should not be a major issue now that weld no longer does a partial export from the OSGI bundle. Sivakumar if this is not the case would you be able to file it under a new issue?

> For Beans with package private constructors, proxy instantiation fails with an Illegal access error as shown below. Since 1.1.0.Beta1 the proxy creation logic in ProxyFactory.addConstructors handles private constructors correctly but doesn't consider package private constructors.
