Hi Naoto,

Since the default locale is being changed even briefly, the test should be run in /othervm.
Add:  @run testng/othervm ...

All java/time/test/java/time/format tests are run in othervm mode by default, defined in java/time/test/TEST.properties.


DateTimeFormatter:1498:
    Can the optimization be retained in the case where z.equals(zone)?
    Move it down to 1508+ and check the zone vs z.

It's not only zone, but also has to check chrono and decimalStyle. In the previous version, I intentionally did not keep the optimization, as it would no longer be "fast" since it would need to check those equality, but at least it would save creating the new DateTimeFormatter instance, so I resurrected it. Here is the updated webrev:

http://cr.openjdk.java.net/~naoto/8246662/webrev.01/

Looks fine to me for the implementation of the method.

It's interesting to observe that the withXXXX methods, as demonstrated in the test, always create a new DateTimeFormatter instance. The Javadoc also said so, e.g. "Returns a copy of this formatter with a new XXXX", and by "a copy" it meant a new instance. Now the localizedBy method also "Returns a copy of this formatter", but it may actually returns this formatter.  Would it confuse users (into thinking they always get a new instance)?  Would we need to amend the javadoc a bit, e.g. indicating it returns this formatter if all of the above aspects are the same? (or otherwise a new instance is returned?)

The localizedBy method seems to me it's not "Unlike the withLocale method" in terms of "producing a different formatter". The difference lies in the attributes demonstrated in this changeset, e.g. zone, chrono and decimalStyle will be from the specified locale in localizedBy, while with the withLocale method, they are inherited. In other words, the withXXXX methods only changes the specified field.

Hello,

Please review the fix to the following issue:

https://bugs.openjdk.java.net/browse/JDK-8246662

The proposed changeset is located at:

https://cr.openjdk.java.net/~naoto/8246662/webrev.00/

This is a regression caused by the fix to JDK-8244245, where the locale related fields in the formatter are now overridden by localizedBy() method. It was only comparing the locale object for the fast path, but it was not sufficient.
