The only issue that I'm aware of that is related to this kind of change is
the requirement to recompile all the classes in the hierarchy when making a
change [0]. If you don't do this its possible for an infinite recursion and
eventual stackoverflow to occur. Now as far as I can tell the
entire hierarchy of Buffer classes are all either package scoped classes,
or they are public classes with package scoped constructors. So I'm not
aware of a way to sub class them without the code being part of the JDK.
This would mean that the subclasses all need to be recompiled, satisfying
the safety criteria.
This is a long standing bug to look at this issue [1].
CharBuffer.subSequence was one case that was retrofitted in 7. As you
note, buffers are not designed to be extended outside of the java.nio
package so this should make a number of options possible.
