Java 7 announcement

OSG community:



To help OSG admins migrate from the now-unsupported free edition of Oracle

JDK 1.6, the OSG Software team has prepared and tested new builds of all

Java packages using Java version 7 (specifically, using OpenJDK 7). Today,

we announce that the new packages are available in (Upcoming) production

and that we are seeking volunteers to be the first to deploy them.



DEPLOYMENT PLAN



The Java 7 packages are available now in the Upcoming area. Eventually, we

will incorporate these updates back into the main OSG Software 3.1 area, so

that they become the default packages for all users. The timeline for this

transition is as follows:



* now - 30 August 2013: Early adopters use packages from Upcoming

* 13 August 2013: Fix remaining known issues in Upcoming (see below)

* 10 September 2013: Release Java 7 packages in main OSG Software 3.1 area



Of course, if a number of issues arise, we may elect to delay the release

until the planned 8 October release.



Please let us know soon if you want and are able to be an early adopter of

the Java 7 packages. We would like your feedback on how the packages are

working for you and how the upgrade process goes. Contact information is

below.



HOW TO INSTALL JAVA 7 PACKAGES



Because sites may not want to install the Java 7 packages right away, they

are available from the Upcoming area, described here:
