> Here is the description:
> Problem: 
> JdbcPOJOPollInputOperator fails with NullPointerException when PostgreSQL driver.
> Problem Description:
> 1) When JdbcPOJOPollInputOperator tries to populateColumnDataTypes, column names retrieved from resultmetadata from database ( this case : Postgres) are all lowercase.
> 2) Whereas columnDatatypes specified in fieldinfos might be in same case.
> 3) Internally hashmap ( nameToType) is used which mismatches if column name and fieldinfo are not in same case. Hence columnDataTypes is empty which causes null exception in activate call.
> Proposed Solution:
> Using similar case for hashmap and column names irrespective of any database used for JdbcPOJOPollInputOperator.
