Hi Liang I think if we maintain multiple versions, for the old version we don’t need add new feature, we only need fix serious bug, for example a serious security problem has not been discovered in the release version.
If we never update for JDK7, users need to be forced to upgrade to JDK8. In some cases, it is unrealistic to upgrade some legacy system to JDK8. For the maintenance version, we can reduce the frequency of the release, for example we can release a version for half a year.
