Java 8 features that are being worked on

 * Community Process (JCP) and is made available for testing and evaluation purposes
 * only. The code is not compatible with any specification of the JCP.

  • Use the following @since tag on all newly added members: "3.9 BETA_JAVA8"

What to do to set up the IDE

This is a work in progress. The contents of the BETA_JAVA8 branch will be updated as the changes are made to the JSR Specification.

If you need any help with this, please contact the JDT/Core team through either the forum or Bugzilla.
