Hi,
I'm using the Jackrabbit OCM library (the current version from the trunk
folder in svn) and I've probably found a bug in
org.apache.jackrabbit.ocm.reflection.ReflectionUtils.
Current version:
public static boolean implementsInterface( Class clazz, Class
interfaceClass ) {
// Try to find the interface class in the interfaces list
if (clazz.getInterfaces() != null )
{
for ( Class foundInterface : clazz.getInterfaces() ) {
if ( foundInterface == interfaceClass ) {
return true;
}
return implementsInterface(foundInterface,
interfaceClass); // *
}
}
// Try to find from the ancestors
if (clazz.getSuperclass() != null)
{
return implementsInterface(clazz.getSuperclass(),
interfaceClass);
}
return false;
}
The line marked by "*" should contain something like this (or similar):
if (implementsInterface(foundInterface, interfaceClass)) {
return true;
}
The current version checks just one interface...
The situation shows up when I try to persist a map field
that has been initialized by java.util.Collections.EMPTY_MAP, so
ReflectionUtils.implementsInterface(java.util.Collections.EMPTY_MAP.getClass
(),
java.util.Map.class) always returns false.
After fixing this method, everything works fine...
Regards
Kamil
