Description

The constructors of java.lang.Integer and java.lang.Double has been deprecated already, see https://docs.oracle.com/javase/9/docs/api/java/lang/Integer.html. The following warnings are printed while compiling Spark:

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.

 The ticket aims to replace the constructors by the valueOf methods, or maybe by other ways.
