-----------------------------
Summary: [Java] Enhance TransferPair related parameters check and
tests
Key: ARROW-6871
URL: https://issues.apache.org/jira/browse/ARROW-6871
Project: Apache Arrow
Issue Type: Bug
Components: Java
Reporter: Ji Liu
Assignee: Ji Liu
{{TransferPair}} related param checks in different classes have potential
problems:
i. {{copyValueSafe}} do not check from index, if from > valueCount, no error is
shown.
ii. {{splitAndTansferPair}} has no indices check in classes like
{{VarcharVector}}
iii. {{splitAndTranserPair}} indices check in classes like UnionVector is not
correct (Preconditions.checkArgument(startIndex + length <= valueCount)),
should check params separately.
iv. some assert usages should be replaced with {{Preconditions}}.
v. should add more UT to cover corner cases.
