-----------------------------
Summary: [Java] ValueVector#accept may has potential cast exception
Key: ARROW-6472
URL: https://issues.apache.org/jira/browse/ARROW-6472
Project: Apache Arrow
Issue Type: Bug
Components: Java
Reporter: Ji Liu
Assignee: Ji Liu
Per discussion
[https://github.com/apache/arrow/pull/5195#issuecomment-528425302]
We may use API this way:
{code:java}
RangeEqualsVisitor visitor = new RangeEqualsVisitor(vector1, vector2);
vector3.accept(visitor, range){code}
if vector1/vector2 are say, {{StructVector}}s and vector3 is an {{IntVector}} -
things can go bad. we'll use the {{compareBaseFixedWidthVectors()}} and do
wrong type-casts for vector1/vector2.
