[jira] [Updated] (ARIES-703) JDKProxyManager cannot proxy blueprint
beans
[ https://issues.apache.org/jira/browse/ARIES-703?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Timothy Ward updated ARIES-703:
-------------------------------
Component/s: (was: Proxy)
Blueprint
Moving this to the blueprint component (where the problem actually is. The proxy component is just doing what it's asked.
It might be a good idea to change the blueprint internals a little such that if the blueprint bean needs to be proxied it is always proxied with the minimal set of interfaces/hierarchy that it needs for that particular call (e.g. injecting into another bean via interface or super-class). This would prevent the "one shot" approach we have now where to proxy beans we have to proxy everything, even if the bean is only referred to by interface in the other beans.

> Components: Blueprint
> Environment: Glassfish 3.1
> Reporter: Balazs Zsoldos

> When there is no ASM between the bundles and aries proxy is installed the default proxy manager is JDKProxyManager. When there is a bean in a blueprint fragment that has for example tx:transaction inside creating the transactional proxy fails with the following stacktrace:

> That means that the interface list is the class of the bean itself that is cannot be an interface. In case of JDKProxy we should derive the interfaces that the bean implements and those interface classes should be passed. However at this level (BeanRecipe) we do not know about the proxy manager...
