Hi all,
Just wonder why ClassCastException is raised at line 496 of LogFactory in
newFactory() method when running as a JUnit test? I found this problem when running
RequiredNameTest in commons-validator. When casting a class to some superclass, does
classloader from other thread form a namespace and so can NOT cast it? Java language
spec seems not regulate this. I have proven this with a small program.
Attached are JUnit test files I use to study this problem.
Regards,
Rice
