Enhanced method handles [JEP-274]

The Enhanced Method Handles JEP-274 was to improve the following listed classes, to make common usage easier with improved optimizations:

  • MethodHandle class
  • MethodHandles class
  • MethodHandles.Lookup class

The listed classes are all part of the java.lang.invoke package, which has been updated as part of the Java 9 platform. The improvements were made possible through the use of lookup refinement and MethodHandle combinations for loops and try...finally blocks.

In this section, we will look at the following regarding JEP-274:

  • Reason for the enhancement
  • Lookup functions
  • Argument handling
