             Summary: [Java] Resolve the ambiguous method overload in 
RangeEqualsVisitor
                 Key: ARROW-6266
                 URL: https://issues.apache.org/jira/browse/ARROW-6266
             Project: Apache Arrow
          Issue Type: Bug
          Components: Java
            Reporter: Liya Fan
            Assignee: Liya Fan


In RangeEqualsVisitor, there are overload methods for both super class and sub 
class. This will lead to unexpected behavior.

For example, if we call RangeEqualsVisitor#visit(v), where v is a fixed width 
vector, the method actually called may be visit(ValueVector), which is 
unexpected.

In general, in the visitor pattern, it is not a good idea to support method 
overload for both super class and sub-class as parameters.
