Hello,

We are currently reviewing an application that is running on the following Java environments:

Device 1
IBM Java 8 Runtime Environment, Standard Edition
Version: 1.8.0_461
IBM build: 1.8.0_461-b11
Mac OS X x64 (SR8 FP50)
Java HotSpot(TM) 64-Bit Server VM (build 25.461-b11, mixed mode)

Device 2
IBM Java 8 Runtime Environment, Standard Edition
Version: 1.8.0_451
IBM build: 1.8.0_451-b10
Mac OS X x64 (SR8 FP45)
Java HotSpot(TM) 64-Bit Server VM (build 25.451-b10, mixed mode)

We would like official clarification from IBM on the following:

  1. Does using these IBM Java 8 Runtime Environment builds require the purchase of any separate commercial or enterprise license for runtime use in an enterprise application?

  2. If no license is required, could an IBM representative please confirm that explicitly?

  3. If a license is required, what exact license/product would apply?

  4. Is there a supported OpenJDK-based alternative that could be used instead for this application, in order to avoid any enterprise licensing concerns?

  5. If yes, are there any IBM-recommended migration considerations or compatibility concerns when moving from these IBM Java 8 builds to OpenJDK?

We are trying to determine whether we can continue using the current runtime as-is, or whether we should plan a move to an OpenJDK distribution.

An official response from an IBM representative would be greatly appreciated.

Thank you.
