25/**
26 * Signifies that a public API (public class, method or field) is subject to
27 * incompatible changes, or even removal, in a future release. An API bearing
28 * this annotation is exempt from any compatibility guarantees made by its
29 * containing library. Note that the presence of this annotation implies nothing
30 * about the quality or performance of the API in question, only the fact that
31 * it is not "API-frozen."
32 *
33 * <p>It is generally safe for <i>applications</i> to depend on beta APIs, at
34 * the cost of some extra work during upgrades. However it is generally
35 * inadvisable for <i>libraries</i> (which get included on users' CLASSPATHs,
36 * outside the library developers' control) to do so.
