Sun's Phipps Slams App Engine's Java Support

Posted by samzenpus on from the you're-both-pretty dept.

narramissic writes "Sun Microsystems' chief open source officer, Simon Phipps, said in an April 11 blog post that Google committed a major transgression by only including support for a subset of Java classes in its App Engine development platform. 'Whether you agree with Sun policing it or not, Java compatibility has served us all very well for over a decade,' Phipps wrote. 'That includes being sure as a developer that all core classes are present on all platforms. Creating subsets of the core classes in the Java platform was forbidden for a really good reason, and it's wanton and irresponsible to casually flaunt the rules.' Phipps characterized his remarks as non-official, saying: 'This isn't something I could comment on on Sun's behalf. My personal comments come purely from my long association with Java topics.'"

    Google's way:

    1. Developer tries to port code
    2. javac throws classNotFound exceptions
    3. Dev:"WTF! java.lang.System is integral!"
    4. Dev is VERY confused since java.lang.System is essential for a basic hello world.

    Citation needed, please. Here's what Google's documentation about java.lang.System says:

    Features of the java.lang.System class that do not apply to App Engine are disabled.

    The following System methods do nothing in App Engine: exit(), gc(), runFinalization(), runFinalizersOnExit()

    The following System methods return null: inheritedChannel(), console()

    An app cannot provide or directly invoke any native JNI code. The following System methods raise a java.lang.SecurityException: load(), loadLibrary(), setSecurityManager()

    What about this is unreasonable? Where does it say that apps will get ClassNotFoundExceptions? Please stop spreading unsubstantiated FUD.
