    Possible duplicate of: DevServer fails after updating to java 6u31

    However, this problem seems to be documented (with solution) here:
    http://code.google.com/p/googleappengine/issues/detail?id=6928

    From the site:

    Workaround – start the GAE with the following JVM parameter:
    -Dappengine.user.timezone=UTC

    (with eclipse, go to "run configuration", under the "Arguments" tab add "-Dappengine.user.timezone=UTC" to the VM arguments line. With maven-gae-plugin, add -Dappengine.user.timezone=UTC to the plugin configuration).
    Good luck, and hopefully Google will support JDK u31 soon enough.
