One of reasons of verifier/classnotfound exceptions is that classes
can't be read from files after security manager is installed - please
see http://issues.apache.org/jira/browse/HARMONY-1226 for minimal test
case.
It is the reason why class can't be loaded with second parameter ==
true but can be loaded with it == false. The class is already in cache
but access to its disk copy is denied.

Ok, I'll try to explain it.
Function vf_resolve_class with true as the second parameter asks class
loader to load a class with a given class name. If the second parameter
equals to false, function just checks if a given class is loaded, and get it
if it is.
The patch claims that if class loader tries to load a given class and fails
and then asks it to lookup among loaded classes it appears to be
successfully loaded. That is a class is failed to load, but it is
successfully loaded in VM. It could work only is a class loader is bugged.
