Parse error: syntax error, unexpected T_DOUBLE_ARROW

[Chrysweel]

I think that there is an internal error in the Bundle.

When I do : Composer Update
I get the following error:

PHP Parse error: syntax error, unexpected T_DOUBLE_ARROW in /var/www/workspace/sdfs2.0/vendor/avalanche123/imagine-bundle/Avalanche/Bundle/ImagineBundle/Controller/ImagineController.php on line 136

Parse error: syntax error, unexpected T_DOUBLE_ARROW in /var/www/workspace/sdfs2.0/vendor/avalanche123/imagine-bundle/Avalanche/Bundle/ImagineBundle/Controller/ImagineController.php on line 136

In my composer.json I have:

"require": {
    "symfony/framework-standard-edition": "2.1.*",
    "friendsofsymfony/facebook-bundle": "dev-master",
    "friendsofsymfony/user-bundle" : "*",
    "friendsofsymfony/comment-bundle" : "2.0.x",
    "friendsofsymfony/rest-bundle" : "dev-master",
    "jms/serializer-bundle": "0.9.0",
    "sonata-project/admin-bundle" : "dev-master",
    "sonata-project/doctrine-orm-admin-bundle" : "dev-master",    
    "sonata-project/user-bundle" : "dev-master",

        "jms/security-extra-bundle": "1.2.*",
        "jms/di-extra-bundle": "1.1.*"

},
"scripts": {
    "post-install-cmd": [
       "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
       "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
       "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
       "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile"
    ],
    "post-update-cmd": [
       "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
       "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
       "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
       "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile"
    ]
},
"minimum-stability": "dev"
}

And in my appKernerl:

public function registerBundles()
    {
        $bundles = array(
        .....
        new Avalanche\Bundle\ImagineBundle\AvalancheImagineBundle(),
