  • 5. JDK 7 ™  All JDK 7 work in done under the Open JDK umbrella  JSRs that should be part of JDK 7 and are a concern for the JDT team: 1. 292 (invokedynamic) 2. 294 (module support) 3. 308 (annotations on type) 4. ? (Project coin) 5. ? (Closure: Project Lambda) 6. ? Maybe more to come  No JSR for Java 7 ™  Open JDK = GPL licence  Incompatible with EPL  The Eclipse Foundation is in discussions with Oracle (formerly Sun) since last September about being able to access documentation under a license that we could use to implement the corresponding part into JDT 5 Copyright © IBM Corp., 2010.
