Subject Re: [DISCUSS] Supported Java version
Date Tue, 26 Feb 2013 20:11:56 GMT

Putting on my systems administrator hat, I consider security updates a significant, if not,
vital feature.  Since Oracle will cease issuing security updates for Java6 at the end of this
month (February 2013), I think support for Java7 becomes compelling if not mandatory.  Since
we will not officially support Java7 in 4.1, our users be forced to run on an unsupported
JRE for 4-6 months.  The question to my mind is not whether or not Java7 is supported in the
next major release (with Java6 deprecated), but can we provide a remediation sooner that would
allow our users to run on a supported JRE?

 Is there anything Java 7 that we really need to use in CloudStack?
