Since Java 9, new features are finally coming again. However, the ecosystem had gotten reliant on certain JDK internals being accessible and stable, while in fact they were neither. That will require some more years to properly transition over. The only feature that really got obsoleted is the Security Manager and the underscore variable name. Primitive wrapper class constructors are on the chopping block next. Most other things are merely being restricted to harden the platform, with ample time to prepare. Edit: LTS hopping is probably an unwise strategy as one will harvest only disadvantages: few updates, no performance improvements, no new features, and complicated migrations when it is time to upgrade. One best upgrades as soon as the new version becomes available (as people did before Java 8) or stays on LTS until the software is retired.
