Alex,

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?

Thanks,
-John
