Subject [jira] [Commented] (HBASE-5261) Update HBase for Java 7
Date Sat, 07 Jul 2012 21:48:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13408785#comment-13408785

Lars Hofhansl commented on HBASE-5261:
--------------------------------------

Yeah, that blog summarizes it nicely.

We need this to *compile* HBase with JDK7. (As explained in the blog, even with -source 1.6
it will not necessarily run on a JDK6, because of missing/changed classes).

We do not need this when we compile HBase with JDK6 and then *run* with JDK7.

But since this option won't hurt anything, being able to compile HBase with JDK7 is nice.

> We need to make sure that HBase compiles and works with JDK 7. Once we verify it is reasonably
stable, we can explore utilizing the G1 garbage collector. When all deployments are ready
to move to JDK 7, we can start using new language features, but in the transition period we
will need to maintain a codebase that compiles both with JDK 6 and JDK 7.
