Summary0000286: SessionSingleton cache serialization
DescriptionThe class APF\core\singleton\SessionSingleton uses the self::$CACHE array to cache its instantiated objects. SessionSingleton inherits from Session, but doesn't declare its own caching array.

The method SessionSingleton::saveObjects() iterates over all entries in self::$CACHE and tries to serialize them. Therefore: as soon as SessionSingleton is used at least once to create an instance of an object, all objects that have been instantiated by either Session or SessionSingleton will be serialized.

SessionSingleton should have its own caching array.
Steps To ReproduceThe following code will throw an exception, which should not be the case.

use APF\core\singleton\Singleton;
use APF\core\singleton\SessionSingleton;
$dir = dirname($_SERVER['SCRIPT_FILENAME']);
$apfClassLoaderRootPath = $dir . '/APF';
$apfClassLoaderConfigurationRootPath = $dir . '/config/APF';
class Foo {
    public function __sleep() {
        throw new Exception();
class Bar {}
TagsNo tags attached.

Hey darkstar,

thanks a lot for your bug report! There is definitely an issue with declaration of the cache container!

I´ll provide a fix for this issue by tomorrow latest.

Question: is there a need for a back port to 3.1? If yes, please let mehr know and I´ll provide a 3.1 fix pack.

ok, thanks! A fix in the git repo would be enough for me, I just noticed it in the 3.1 release.
