We were running Alpha Testing Using JavaSE Embedded, based off of JavaSE 7 (Not sure what Update version at the moment)

I would imagine that WPI would like to stick with Java 7 for 2015 because that is what will be the most tested by that time. However, sticking with 7 is not written in stone, and if they are comfortable enough, they can upgrade to JavaSE Embedded 8.

As for the Differences between JavaSE and JavaSE Embedded. Don't think of it this way because it will be hard to convince yourself you need JavaSEEmbedded. Instead think of it like this: JavaSE Embedded, is the upgrade of Java ME CLDC.

Java SE Embedded derives from JDK, but provides specific features and support for the embedded market on a limited set of supported platforms. The embedded-specific features and support include additional platforms, small footprint JREs (optional files removed), headless configurations, and memory optimizations.


The reality is Java ME CDC and CLDC technology is Oracle's legacy technology that addresses embedded devices that had more than 1MB RAM and 10MB ROM. "Java SE Embedded is a new generation Java Embedded Platform that addresses devices that have [a little more] resources, but also allows them to access the latest APIs and functionality as is present in JavaSE. Truthfully, Java ME and Java SE Embedded address different segments of the embedded market. The Java ME CLDC and CDC offerings are designed for resource-limited devices including cell phones, handsets and media players. The APIs of CLDC and CDC are more limited than Java SE but enable these ME offerings to support devices with small footprints. Java SE Embedded provides the rich functionality of Java SE and is targeted at higher-end embedded devices - generally, those devices with at least 32MB RAM and 11MB - 20MB of ROM for a Linux/ARM platform." - From Oracle.

Hope this helps,
