MyBatis Several potential NullPointerException bugs.

Hi all,

Our tool has found several potential NPE bugs.

In method resolveGetterConflicts If the variable winnerMethod winner = null; is set to null and List<Method> is empty. Then addGetMethod(propName, winner, isAmbiguous); will be executed and variable winner is null. These are several uses of the variable in method addGetMethod, which may cause NullPointerException.

Thanks.

This is about org.apache.ibatis.reflection.Reflector, right? I think List<Method> can never be empty. See addMethodConflict(). If you still think it can throw NullPointerException, please provide an example class that reproduces the exception.
