ReflectionHelper.getValue fails to retrieve values from methods defined on a parent
interface
---------------------------------------------------------------------------------------------
Key: HV-257
URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-257
Project: Hibernate Validator
Issue Type: Bug
Components: validators
Affects Versions: 4.0.0.GA, 4.0.0.CR1, 4.0.0.Beta3, 4.0.0.Beta2, 4.0.0.Beta1,
4.0.0.Alpha3, 4.0.0.Alpha2, 4.0.0.Alpha1, 3.1.0.GA, 3.1.0.CR2, 3.1.0.CR1, 3.0.0.ga, Bundle
3.2.1
Environment: hibernate-validator 4.0.0.CR1
Reporter: Amir Kibbar
I've defined an interface A with method foo with a constraint annotation on it.
I've then defined an interface B that extends interface A.
I've created a proxy (invocation handler) that implements interface B at runtime.
When I try to validate the proxy object I get an IllegalAccessException because the
modifier on the method the ReflectionHelper.getValue() is trying to invoke has the
"public abstract" modifiers.
This can easily be solved if the getValue() will set method.setAccesible(true) before
attempting to invoke it (and then reset it to the previous value obviously).
thanks,
Amir

Hi,
i'm having problems creating an appropriate test case, but here's my stack trace,
perhaps it is something I'm doing wrong?
take a look at the very bottom of this stack trace to see the issue i'm reporting:

I've defined an interface A with method foo with a constraint annotation on it.
I've then defined an interface B that extends interface A.
I've created a proxy (invocation handler) that implements interface B at runtime.
When I try to validate the proxy object I get an IllegalAccessException because the
modifier on the method the ReflectionHelper.getValue() is trying to invoke has the
"public abstract" modifiers.
This can easily be solved if the getValue() will set method.setAccesible(true) before
attempting to invoke it (and then reset it to the previous value obviously).

Ok - my scenario was not exact - I hadn't noticed that the "A" interface was
not public. I'm attaching a test case that reproduces the problem.

]
Hardy Ferentschik resolved HV-257.
----------------------------------
Resolution: Fixed
Fix Version/s: 4.0.1
Added a fix to ReflectionHelper.setAccessibility.
Now we also call setAccessible in case of public abstract members. If you proxy an
interface using java.lang.reflect.Proxy
per default you will get a IllegalAccessException since you are not allowed to access
abstract methods.
Seems odd. One could argue that the proxy 'is' the implementation for the
interface method and hence they
should be accessible. Maybe this is a JVM bug !?

"public abstract" modifiers.
This can easily be solved if the getValue() will set method.setAccesible(true) before
attempting to invoke it (and then reset it to the previous value obviously).
thanks,
Amir

New subject: [Hibernate-JIRA] Commented: (HV-257) ReflectionHelper.getValue fails to retrieve values from methods defined on a parent interface

--------------------------------
Hardy,
your argument makes a lot of sense to me. However, the workaround is so simple - so why
bother with JVM bug? :)
thanks for the fix.

ReflectionHelper.getValue fails to retrieve values from methods
defined on a parent interface
---------------------------------------------------------------------------------------------
Key: HV-257
URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-257
Project: Hibernate Validator
Issue Type: Bug
Components: validators
Affects Versions: Bundle 3.2.1, 3.0.0.ga, 3.1.0.CR1, 3.1.0.CR2, 3.1.0.GA,
4.0.0.Alpha1, 4.0.0.Alpha2, 4.0.0.Alpha3, 4.0.0.Beta1, 4.0.0.Beta2, 4.0.0.Beta3,
4.0.0.CR1, 4.0.0.GA
Environment: hibernate-validator 4.0.0.CR1
Reporter: Amir Kibbar
Fix For: 4.0.1
Attachments: validator-test-case.tar.gz
I've defined an interface A with method foo with a constraint annotation on it.
I've then defined an interface B that extends interface A.
I've created a proxy (invocation handler) that implements interface B at runtime.
When I try to validate the proxy object I get an IllegalAccessException because the
modifier on the method the ReflectionHelper.getValue() is trying to invoke has the
"public abstract" modifiers.
This can easily be solved if the getValue() will set method.setAccesible(true) before
attempting to invoke it (and then reset it to the previous value obviously).
thanks,
Amir
