Subject [jira] [Commented] (DERBY-5469) Make it possible to build Derby if you are on Mac OS X and your JDK is JDK 7
Date Mon, 24 Oct 2011 07:34:32 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5469?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13133870#comment-13133870
] 

Knut Anders Hatlen commented on DERBY-5469:
-------------------------------------------

I see similar differences on Solaris. "ant -q all" takes ~40 s when JAVA_HOME points to JDK
6, and ~65 s when it points to JDK 7. I also see this when running without the patch, so I
don't think there's a problem with the patch.

Another observation: If I remove the source="..." and target="..." attributes from all the
javac targets in the build files, the JDK 7 build runs as fast as the JDK 6 build. Perhaps
javac in JDK 7 is less optimized for compiling classes with source and target level 1.4.
