Subject [jira] [Commented] (HADOOP-11875) [JDK9] Renaming _ as a one-character identifier to another identifier
Date Thu, 27 Jul 2017 05:41:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11875?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16102742#comment-16102742
] 

Akira Ajisaka commented on HADOOP-11875:
----------------------------------------

Thanks [~chris.douglas] and [~stevel@apache.org] for the comments.

bq. To be clear, this is adding a second copy of Hamlet's generated code in a different package?
Yes.

bq. I note there is actually one possible backwards compatibility strategy, producing a special
jar of old hamlet stuff which people could use until they've moved. But that might just discourage
people from migrating, which is fine if they build and run on java 8, but if anything is distributed
to run on java 9, things will break downstream then.
Yes, it can keep backward compatibility, however, producing a special jar seems overkill and
it might discourage people from migrating.

Can I commit the latest patch to trunk based on [~chris.douglas]'s +1?

> From JDK9, _ as a one-character identifier is banned. Currently Web UI uses it. We should
fix them to compile with JDK9. https://bugs.openjdk.java.net/browse/JDK-8061549
