Hello everyone,

proxyReturnClass is always null, so interfacesToProxyClassesMap will contain 
null values only. Adding newProxyReturnClass should be correct.

This bug does not affect functionality, but probably decreases performance 
because you get "cache misses" all the time.

Best regards,
David.
