Behat/BehatBundle — Issue #29: Context class "" not found

Because of this two lines:

https://github.com/Behat/BehatBundle/blob/master/Resources/config/behat_bundle.xml#L6
https://github.com/Behat/BehatBundle/blob/master/Console/Processor/ContextProcessor.php#L49

Config pass pass empty string, and ContextProcessor have comparison in strict mode (!==) thus ContextProcessor returns empty sting as "contextClass".
