False positives in Comparator on default values

At the moment I found only one way how to work with default values

/**
 * @var string $isActive
 *
 * @Column(name="isActive", type="boolean", nullable=false)
 */
private $isActive;

and then in the construct I use something like $this->setIsActive(true);
on db level it looks like "isActive BIT default 1"
But the problem happened when I try to compare schemas for migrations. It always false positives on defaults.

How to set defaults for prevent false positives in Comparator?
