Sivakumar Thyagarajan commented on WELD-737:
--------------------------------------------
Hi Stuart: I understand the reasons for not doing this and yes, with the fixing of
JASSIST-104 and WELD-570, the partial exports and the corr classloader leaks have been
fixed. However I was wondering how implementations that use the weld osgi-bundle could
support this package private constructor usecase. They would also need to have a fragment
based approach like the one GlassFish uses [1] to make the extra javassist packages used
by the proxies available to the application classloader. Is this right and recommended?

Proxy instantiation fails with IllegalAccessError for Beans with
package private constructor
--------------------------------------------------------------------------------------------
Key: WELD-737
URL: https://jira.jboss.org/browse/WELD-737
Project: Weld
Issue Type: Bug
Components: GlassFish Integration, Proxies
Affects Versions: 1.1.0.Beta1
Reporter: Sivakumar Thyagarajan
Assignee: Stuart Douglas
Labels: beans, constructor, initializer, proxy, scoped
Fix For: 1.1.0.CR1
Attachments: package-private-constructor-issue.tar.bz2, ProxyServicesImpl.java
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.
