Ephesoft Transact switch from Oracle JDK to OpenJDK: Frequently Asked Questions

Oracle has announced a decision to require a commercial (chargeable) license to be entitled to receive updates to the Oracle JDK. While there is a low likelihood this would impact customers in the future, Ephesoft has taken the decision, for the long term benefit of customers, to remove this dependency on the Oracle JDK.

As a result of this decision, Ephesoft is switching from using the Oracle JDK in Ephesoft Transact to incorporating OpenJDK. This switch will eliminate the Oracle JDK dependency and remove the potential requirement to purchase a separate chargeable JDK license from Oracle in the future.

This page provides answers to common questions about Ephesoft Transact and the switch from Oracle JDK 8.0 to Open JDK, this would become effective with the release immediately after Ephesoft Transact 2019.1.

Q1:      Why is Ephesoft switching from the Oracle JDK to Open JDK?

A1:       Ephesoft Transact has bundled and shipped the Oracle JDK with all versions of Ephesoft Transact including the currently supported versions of through 2019.1.  Transact installs and leverages Oracle’s JDK Version 8.0.

Effective January 1, 2019, Oracle has changed their licensing for future versions of the Oracle JDK. Oracle is requiring a (chargeable) commercial license for all future updates and patches to the Oracle JDK Version 8. Customers on Oracle JDK Version 8.0 are not required to upgrade or purchase a commercial license from Oracle.

Ephesoft has decided to replace the Oracle JDK with the (non-chargeable) Open JDK. The next release of Ephesoft Transact will transition to utilizing the OpenJDK instead of the Oracle JDK.

Q2:      Do customers need to upgrade Ephesoft Transact?

A2:       No — All currently supported versions of Ephesoft Transact ( – 2019.1) are supported and will remain in accordance with our published calendar on the Oracle JDK Version 8.0.

A4:       No — A license is only required to receive updates of the Oracle JDK. Ephesoft Transact does not require these updates in order to function.

Q5:      Can I use the OpenJDK with 2019.1 or prior versions?

A5:       Ephesoft is currently certifying OpenJDK with the next Ephesoft Transact release. The first certification will be with this version. No certifications with prior versions are planned at this time.

  1. Upgrade to next planned release, thereby utilizing OpenJDK and removing the Oracle JDK dependency. (Recommended)
