Is it possible to see the order in which classes are loaded by the

If so, what kind of class structure would I need to determine if the
class loader is behaving in a PARENT_FIRST or PARENT_LAST mode?
Well, if you run java -verbose:gc, java will print out every class load
in order to stderr.
Pragmatically from within the code, determining the order requires
either some major reflection hacks or using your own custom class loader.
That latter will kind of destroy the point, won't it? The standard Java
ClassLoaders are PARENT_FIRST by specification.
<http://java.sun.com/javase/6/docs/api/java/lang/ClassLoader.html>
When requested to find a class or resource, a ClassLoader instance
will delegate the search for the class or resource to its
parent class loader before attempting to find the class or resource itself.
Someone must be playing games with their class loader implementations for the
OP to have a problem. Writing their own is likely not to reveal what the
third-party loaders are doing.
Is that correct, OP, as to your problem?
If these third-party class loaders are doing "PARENT_LAST", aren't they
violating the specification?
Shouldn't that vendor be slapped down for that?
