@Desc extraction breaks on certain line endings

[iquito]

Q	A
Bundle version	1.3.1
Symfony version	3.1.7
PHP version	7.0

Extracting translations & using @Desc does not seem to always work - I found out that the following does not make use of the @Desc ('email.payment_amount' is saved as <source> instead of "Amount"):

/**
 * @Desc("Amount")
 */
'label' => $this->translator->trans('email.payment_amount', [], 'domain') . ':',

While the following does work:

/**
 * @Desc("Amount")
 */
'label' => $this->translator->trans('email.payment_amount', [], 'domain'),

The . ':' at the end of the line seems to cause some problem in extracting the @Desc value. Maybe other characters or additions to a line cause the same, which makes the translation extraction easy to break.

By the way, the following does work:

'label' => 
  /**
   * @Desc("Amount")
   */
  $this->translator->trans('email.payment_amount', [], 'domain') . ':',

So @Desc just seems to break in some situations, but not in others (it is not obvious to me why/when it works). The problem is: you never know if it works or not until you extract the translations, so the uncertainty is quite a pain.

I also saw that there is a pull request to improve the Desc annotation: https://github.com/schmittjoh/JMSTranslationBundle/pull/233 - maybe this would also solve this issue?
