Beta Features

Features marked with the @Beta annotation at the class or method level are subject to change. They might be modified in any way, or even removed, in any major release. You should not use beta features if your code is a library itself (that is, if your code is used on the CLASSPATH of users outside your own control).

Deprecated Features

Deprecated non-beta features will be removed eighteen months after the release in which they are first deprecated. You must fix your usages before this time. If you don’t, any type of breakage might result, and you are not guaranteed a compilation error.
