[jira] [Created] (PHOENIX-6156) IndexOutOfBoundsException,
Expression 'AND' with 'RVC'
JUIL CHO created PHOENIX-6156:
---------------------------------
Summary: IndexOutOfBoundsException, Expression 'AND' with 'RVC'
Key: PHOENIX-6156
URL: https://issues.apache.org/jira/browse/PHOENIX-6156
Project: Phoenix
Issue Type: Bug
Components: core
Affects Versions: 4.14.1
Reporter: JUIL CHO
Bug in WhereOptimizer$KeyExpressionVisitor.intersectTrailing included in [PHOENIX-3383](https://issues.apache.org/jira/browse/PHOENIX-3383) patch
Using AndExpression with RVCExpression in a query results in an exception.
Exception occurs when the value of the ID2 column is 8 bytes or more.
This is because of the way bytes are read in the function below.

intersectTrailing function reads byte : 8byte > 8byte > 4byte > amount
If the value of the ID2 column is more than 8 bytes, the delimeter is encountered when reading the'amount' byte, and the loop is executed once more.
