-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi All
For Quantal the default implementation of Java has been switched from OpenJDK 6 to OpenJDK 7 in-line with objectives agreed in [1]. This basically means that if you install default-[jdk|jre|jre-headless] or you install OpenJDK 6 and 7 then Ubuntu will prefer OpenJDK 7 by default. This is an important change as OpenJDK 7 is much more closely aligned with Oracle Java 7; performance and compatibility should be comparable on x86 based architectures. This change has been in place for some time now but as we approach Beta-2 it would be great if anyone who uses Java on a regular basis, either for development or to run applications, could do some more extended testing to ensure that this transition is still going nice and smoothly. If you find any problems please report bugs and tag with 'java7-regression-potential'. We still have a few outstanding FTBFS with OpenJDK 7 as default Java - see [2] if you have some time to help out. There are also have a large number of potential bytecode compatibility issues (packages which build with OpenJDK 7 but don't set the flags to ensure that the code built is compatible with Java 6 as well) - see [3] for the full list of impacted packages which when re-built exhibit this problem. I'm also in the progress of assessing the binary packages already in the archive for quantal which might already have this issue (which should be fixed as a priority). See [4] for more details on how to resolve both of these types of issues. Thanks in advance for any time you can spare either testing or fixing bugs.
