Composer-Installed PHPUnit is used when trying to use PHPUnit from a PHAR

[sebastianbergmann]

When PHPUnit is installed via Composer and Composer's vendor/autoload.php is used as PHPUnit's bootstrap then the Composer-installed PHPUnit will be used instead of the one actually invoked, for instance one invoked from a PHAR:

$ cat composer.json 
{
    "require-dev": {
        "phpunit/phpunit": "~3.7"
    }
}


$ ./vendor/bin/phpunit --version
PHPUnit 3.7.38 by Sebastian Bergmann.


$ php phpunit.phar --version    
PHPUnit 4.4.5 by Sebastian Bergmann.


$ php phpunit.phar --bootstrap vendor/autoload.php tests
PHPUnit 3.7.38 by Sebastian Bergmann.

Configuration read from /home/sb/test/phpunit.xml

That's the expected behavior currently, isn't it?

It was discussed in one of the existing issues already. The only way to "force" the code of the .phar would be to front-load all PHPUnit files into memory, so that the classloader is no longer triggered.
