> 1. RDD.scala:240: constructor Integer in class Integer is deprecated: see
> corresponding Javadoc for more information.
> 2. MutableProjectionSuite.scala:63: constructor Integer in class Integer is
> deprecated: see corresponding Javadoc for more information.
> 3. UDFSuite.scala:446: constructor Integer in class Integer is deprecated:
> see corresponding Javadoc for more information.
> 4. UDFSuite.scala:451: constructor Double in class Double is deprecated: see
> corresponding Javadoc for more information.
> 5. HiveUserDefinedTypeSuite.scala:71: constructor Double in class Double is
> deprecated: see corresponding Javadoc for more information.
> {code}
> The ticket aims to replace the constructors by the valueOf methods, or maybe
> by other ways.
