[jira] [Created] (FLINK-4665) Remove boxing/unboxing to parse a primitive

Alexander Pivovarov created FLINK-4665:
------------------------------------------

             Summary: Remove boxing/unboxing to parse a primitive
                 Key: FLINK-4665
                 URL: https://issues.apache.org/jira/browse/FLINK-4665
             Project: Flink
          Issue Type: Bug
          Components: Java API
            Reporter: Alexander Pivovarov
            Priority: Trivial


I found the following issues with boxing/unboxing and Integer

1. Current code doing boxing/unboxing to parse a primitive - It is more efficient to just call the static parseXXX method.

2. boxing/unboxing to do type cast

3. new Integer instead of valueOf - Using new Integer(int) is guaranteed to always result in a new object whereas Integer.valueOf(int) allows caching of values to be done by the compiler.
