Error : Class 'Doctrine\Common\Lexer' not found

[Ekion-1]

I'm receiving this error when trying to call $lexer = new Lexer($prefixData[$loopCounter]->regex);. Is this a known issue?

[Ekion-1]

It appears as though the import in Lexer.php should be

use Doctrine\Common\Lexer\AbstractLexer as BaseLexer;

instead of

use Doctrine\Common\Lexer as BaseLexer;
