Message:
--------------------------------------------------------------
Pete has reported a failure in CDI testsuite against the AS trunk
https://jira.jboss.org/jira/browse/JBAS-7676. The testcase involves a @Stateless annotated
EJB. Apart from this annotation, the EJB class also has one other annotation. Here's
how the EJB class and its related classes looks like:
package org.jboss.jsr299.tck.tests.definition.qualifier.enterprise;
@Stateless
public class BorderCollie extends LongHairedDog
implements BorderCollieLocal
{
}
package org.jboss.jsr299.tck.tests.definition.qualifier.enterprise;
@Hairy(clipped=false)
class LongHairedDog
{
}
package org.jboss.jsr299.tck.tests.definition.qualifier.enterprise;
@Target({java.lang.annotation.ElementType.TYPE, java.lang.annotation.ElementType.METHOD,
java.lang.annotation.ElementType.PARAMETER, java.lang.annotation.ElementType.FIELD})
...//removed irrelevant stuff
@interface Hairy
{
public abstract boolean clipped();
}
During annotation scanning of this EJB class, it runs into this error, which causes the
EJB metadata of this class to be messed up and the deployment failing:

The root cause of this issue seems to be a problem in JBREFLECT, which runs into issue
trying to create annotation value information out of a non-public annotation (notice that
"Hairy" in the above example is non-public).
I was able to reproduce this issue with a simple testcase in JBREFLECT trunk:

Is there a way to disable Java language access check for the methods through JBREFLECT
project? Or does that have to be done (selectively) through the underlying
(ReflectMethodInfoImpl) impl?
