  Interface and Description
  com.google.common.util.concurrent.FutureFallback This interface's main user, `Futures.withFallback`, has been updated to use `AsyncFunction`. We recommend that other APIs be updated in the same way. This interface will be removed in Guava release 20.0.
  com.google.common.io.InputSupplier For `InputSupplier<? extends InputStream>`, use `ByteSource` instead. For `InputSupplier<? extends Reader>`, use `CharSource`. Implementations of `InputSupplier` that don't fall into one of those categories do not benefit from any of the methods in `common.io` and should use a different interface. This interface is scheduled for removal in December 2015.
  com.google.common.collect.MapConstraint Use `Preconditions` for basic checks. In place of constrained maps, we encourage you to check your preconditions explicitly instead of leaving that work to the map implementation. For the specific case of rejecting null, consider `ImmutableMap`. This class is scheduled for removal in Guava 20.0.
  com.google.common.io.OutputSupplier For `OutputSupplier<? extends OutputStream>`, use `ByteSink` instead. For `OutputSupplier<? extends Writer>`, use `CharSink`. Implementations of `OutputSupplier` that don't fall into one of those categories do not benefit from any of the methods in `common.io` and should use a different interface. This interface is scheduled for removal in December 2015.

  Class and Description
  com.google.common.collect.MapConstraints Use `Preconditions` for basic checks. In place of constrained maps, we encourage you to check your preconditions explicitly instead of leaving that work to the map implementation. For the specific case of rejecting null, consider `ImmutableMap`. This class is scheduled for removal in Guava 20.0.
  com.google.common.base.Objects.ToStringHelper Use `MoreObjects.ToStringHelper` instead. This class is scheduled for removal in June 2016.

This method will be removed in Guava release 20.0.
  com.google.common.io.ByteArrayDataOutput.writeBytes(String) This method is dangerous as it discards the high byte of every character. For UTF-8, use `write(s.getBytes(Charsets.UTF_8))`.
  com.google.common.io.LittleEndianDataOutputStream.writeBytes(String) The semantics of `writeBytes(String s)` are considered dangerous. Please use `LittleEndianDataOutputStream.writeUTF(String s)`, `LittleEndianDataOutputStream.writeChars(String s)` or another write method instead.
