History

After Oracle acquired Sun we replanned JDK 7 according to the"Plan B" proposal inorder to accelerate its release while maintaining performance andquality. Features that needed more time to mature were deferred toJDK 8 or later releases as explainedhere. A handful ofsmall, high-impact features which were not previously part of theplan but were finished, or nearly so, were added to therelease.

The high-level schedule for the endgame of the release was asfollows:
