java -version output for JDK8

[Kumar Srinivasan]

Hi Omair,

>>> Also, the lines after "java version" make OpenJDK explicit, no? Is this
>>> second line not sufficient to distinguish OpenJDK vs closed builds?
>>>
>>> # java -version
>>> java version "1.7.0_25"
>>> OpenJDK Runtime Environment (fedora-2.3.10.3.fc19-ppc64)  <--- this line
>>> OpenJDK 64-Bit Zero VM (build 23.7-b01, interpreted mode)
>> we needed to account for java -fullversion as well, which btw. is a one
>> liner.

Changing any of these lines is very painful, because  too many scripts 
and tests have
made assumptions on these lines, and some of these are System properties 
which
are baked at build time.

I  checked this on our internal jdk build and it is correct,

% xxxxxxxxx/bin/java -version
openjdk version "1.7.0"
OpenJDK Runtime Environment (build 1.7.0-b146)
OpenJDK Server VM (build 21.0-b16, mixed mode)

Unfortunately no, this dates back to pre OpenJDK and Sun days.
