Hi Chris,

Yes. I just updated the CSR, adding the description in the compatibility risk:

https://bugs.openjdk.java.net/browse/JDK-8215305

Hi Chris,

Yes, it will affect the behavior of those methods. This has been discussed 
within the JLS folks, and their understanding was that the risk is minimal and 
OK to proceed. I was not involved in the discussion, but here are the reasons I 
can think of.

Ok. Should the CSR be updated to indicate this?

- The Currency Symbols range is very limited (U+20A0-U+20CF)
- The change is to allow the code point, not the way around, so existing 
identifiers are guaranteed to work.
- Apart from this CSR, this kind of behavior change is common when a Unicode 
upgrade is done.

Sure, all good and valid reasons.

Will compilations with `--release N-1` wind back the set of allowable
identifiers?  It possibly should, if so how does one do similar when/if
the set of currency characters is expanded in an update release?

-Chris.

Hello,

Please review the fix to the following issue (and its approved CSR):

https://bugs.openjdk.java.net/browse/JDK-8215303
https://bugs.openjdk.java.net/browse/JDK-8215305

The proposed changeset is located at:

http://cr.openjdk.java.net/~naoto/8215303/webrev.00/
I think this is a positive change, but for clarity ( since I cannot find it
in the CSR ), will this change have an impact on the set of allowable
characters that can be used as identifiers, i.e. isJavaIdentifierStart,
isJavaIdentifierPart?
-Chris.
