Subject [jira] [Commented] (HADOOP-11875) [JDK9] Renaming _ as a one-character identifier to another identifier
Date Fri, 03 Mar 2017 12:11:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11875?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15894233#comment-15894233

Steve Loughran commented on HADOOP-11875:
-----------------------------------------

Looking at this. We'll have to get the yarn & MR projects to review, as they are the main
users

otherwise, I don't think the new package should be "hamlet4java9"; many decades in the future,
having a "java9" reference will seem quaint in stack traces. Just call it "hamlet2"

> 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
