Subject [jira] [Commented] (DERBY-6856) Make it possible to build Derby using JDK 9
Date Mon, 08 Feb 2016 08:11:39 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6856?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15136684#comment-15136684
] 

Knut Anders Hatlen commented on DERBY-6856:
-------------------------------------------

Hopefully, Ant's javac task gets support for the new -release option before or around the
time JDK 9 gets out. If not, I suppose we can always add {{<compilerarg line="-release
8" compiler="javac1.9"/>}} to the javac targets in our build scripts. (The "javac1.9" compiler
alias is only recognized by Ant 1.9.5 or newer.) I agree that reviving PropertySetter is not
a good idea now that the JDK is about to add a new and better mechanism for cross-compilation.

>             Project: Derby
>          Issue Type: Improvement
>          Components: Build tools
>    Affects Versions: 10.12.1.1
>            Reporter: Rick Hillegas
>         Attachments: derby-6856-01-ab-addShardingKey.diff, derby-6856-01-ac-cleanup.diff

> Derby can't be built with JDK 9. Java 9 introduces new JDBC classes like java.sql.ShardingKey
and methods which refer to these new classes.
> In addition, project Jigsaw has created a new way to name classes (see http://openjdk.java.net/jeps/220).
This breaks the PropertySetter build tool which we use so that old JVMs can compile Derby
and so that Derby can be compiled to run on old JVMs.
> It is likely that we will need to leave this issue open throughout the development cycle
of Java 9.
