Chen,
thank you for your approval for a DRAFT PR.
Following your proposal, I have published a DRAFT PR at
https://github.com/openjdk/jdk/pull/25432 so everybody can see what
the actual intended code change looks like, and better focus on that
actual code change and its risks and benefits. The intention of that
DRAFT PR explicitly is NOT to request code reviews, but solely to
serve as a publicly visible piece of code to support the ongoing
discussion here on this mailing list.
TARGET VERSION: 26
As we are near to JDK 25 GA, the target is inclusion into JDK 26 or
later, so no need to rush. Nevertheless, I would be happy if everybody
comments ASAP (at least briefly) to keep this discussion alive.
PRELIMINARY RISK ANALYSIS: LOW
Writer was retrofitted to implement Appendable in JDK 5 with the 3-arg
append documented to behave "in exactly the same as ..." the
write(String) method. That's 20 years of subclasses that might be
depending on this behavior. Also 20 years of subclasses that may depend
on the 3-arg append calling the 1-arg append. So my initial reaction is
that the risk may not be low and this proposal will require significant
analysis of Writer implementations before the compatibility risk can be
assessed.
