Subject [jira] [Commented] (ACCUMULO-905) Switch to Java 1.7
Date Fri, 14 Dec 2012 18:34:12 GMT

Keith Turner commented on ACCUMULO-905:
---------------------------------------

I was looking at the release notes for Java 7.  Its up to update 10 now.  I may have missed
something, but the last release that had bug fix that seemed possibly concerning was u5. 
Some bug where the JVM would crash when PermGen was full, not sure if this bug was  big deal
or not.

bq. There are known JDK 1.7 and zookeeper 3.4 issues.

Can you elaborate?

> As 1.7 becomes the default Java in more and more operating systems, and security-related
bugfixes and other fixes in Java itself are targeted more towards newer versions, rather than
maintaining older versions, it would be prudent to switch to using 1.7 as our target platform.
> This change would allow us to leverage some of the newer features of Java.
> This change can be established at the beginning of the development cycle for Accumulo
1.6.0, so that we can immediately begin taking advantage of the new Java features in 1.6.0
features after 1.5.0 is released.
