Hi Everyone, This is an important note for anyone still deploying Java 6 applications on Google App Engine.
As part of our previously announced plan<https://groups.google.com/forum/#!topic/google-appengine/xxXd6NftS1Q>to fully upgrade App Engine to Java 7 - from the next release App Engine will no longer allow applications to be deployed as Java 6. Running Java 6 applications will continue to run, and you can deploy your application as Java 7. Java 7 is backwards compatible with Java 6, as well as providing a number of benefits to developers. Please refer to the Oracle white paper on Java 7 and Java 6 compatibility for additional details: http://www.oracle.com/technetwork/java/javase/compatibility-417013.html *How do I know if I am still deploying Java 6 code?* You can see if your app is running in Java 6 or Java 7 from the Versions section of the App Engine Admin console. If you are using a version of the App Engine for Java SDK later than 1.7.8, and you are not explicitly deploying to Java 6 using the --with_java6 flag, then you are already deploying Java 7 code. *How do I deploy my app as Java 7?* Update your SDK to a recent version (1.7.8 or higher), and deploy your app (and make sure you’re not using the --with_java6 flag). We recommend deploying your to a non-default version first to double check that everything works as expected. If you still absolutely need to deploy Java 6 applications, you may request a temporary exemption from this policy for your application from this form:http://goo.gl/ycffXq. We will only accept exceptions for applications that are (a) are Premier or have billing enabled, and (b) have a provably demonstrated compatibility problems running their application with Java 7. Please also note that it may take us a couple of days to process your application. We’ve worked hard to make this upgrade process as transparent as possible. Today, thousands of Java 6 applications on Google App Engine already have migrated successfully to Java 7, and for the vast majority the upgrade has been entirely transparent and required no changes to code. If you have any questions about our Java 6 to Java 7 upgrade, you can reach us at google-appengine-java-6-to-7-migrat...@googlegroups.com -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
