Technically this vote has had enough +1s to close it but let me try to
address your concern by repeating and elaborating the alleged

Clirr whines about a protected field that's been removed from two
classes in the tar package.  The type of this protected field has been
TarBuffer which has been removed, was package private and didn't
implement any interface.  Clirr does not raise an error because of
TarBuffer being removed as it doesn't consider the class a part of the
public API.

The only people who may get bitten by this change must have written
subclasses of one of the Tar*Stream classes and put them into the same
package that we use in order to gain access to a non-public type.
