In order to remain current, each Eclipse release targets reasonably current versions of the underlying operating environments. This project depends upon on the Platform and other projects, which are mostly "pure" JavaTM. The 4.5 release of the Eclipse Platform Project is written and compiled against version 1.6 of the Java Platform APIs, and targeted to run on version 1.6 of the Java Runtime Environment, Standard Edition. This project will target the same Java version as EMF Core, which currently requires Java 6. Eclipse Platform SDK 4.5 will be tested and validated on a number of reference platforms. This project will be tested and validated against a subset of those listed for the platform.
