[Metadata] PHP warning only when unittesting

[pyrech]

Since few days, I have a weird bug when unitesting my rest api based on SF2. The bug doesn't happen when using the api but only when unitesting it.

The exception thrown comes from a PHP warning (undefined offset: 14) at src/JMS/Serializer/Metadata/ClassMetadata.php#L255:

[2014-03-28 21:50:42] request.CRITICAL: Uncaught PHP Exception PHPUnit_Framework_Error_Notice: "Undefined offset: 14" at D:\my-repos\vendor\jms\serializer\src\JMS\Serializer\Metadata\ClassMetadata.php line 255 {"exception":"[object] (PHPUnit_Framework_Error_Notice: Undefined offset: 14 at D:\\my-repos\\vendor\\jms\\serializer\\src\\JMS\\Serializer\\Metadata\\ClassMetadata.php:255)"} []

After running a composer update I have the same problem in my centos server too, not only Windows. I failed to detect which upgraded package is causing the issue. It's really a strange bug.

@pyrech Try to remove the dev-/prod-folder from cache as the structure has been changed some time ago. I suffered from the same issue and this helped.

Thank you very much, it works now. Clear the cache is not something I'm used to do when I run into problems.
