[jira] [Created] (ARROW-4669) [Java] No Bounds checking on ArrowBuf.slice

Jacques Nadeau created ARROW-4669:
-------------------------------------

             Summary: [Java] No Bounds checking on ArrowBuf.slice
                 Key: ARROW-4669
                 URL: https://issues.apache.org/jira/browse/ARROW-4669
             Project: Apache Arrow
          Issue Type: Bug
            Reporter: Jacques Nadeau


While reviewing some code I realized that there is no bounds checking on ArrowBuf slicing. Example negative test case that should pass but is currently failing can be found here:

It may be that this doesn't cause more problems because the index checks do exist on memory access but fixing this would make it much easier to understand where a code mistake was made.
