    // In Tomcat 6 the testEmptyArray() test fails with a java.io.EOFException.
    //
    // Backporting r1143022 (support for 0-length array in deserialize())
    // to Tomcat 6 is probably a bad idea, as
    //
    // 1. All valid use cases already check for (length == 0) case before
    // calling deserialize(), so adding a second check there is redundant
    //
    // 2. It will change behaviour of GroupChannel.messageReceived(),
    // as deserialize() call there will no longer fail with an exception.
    //
    // The change will be that instead of logging an error and returning
    // doing nothing, the messageReceived() method will go on and will notify
    // a channelListener. I do not know whether the listener is able to handle
    // a null argument.
