optimize imports moves import statements before file header Follow

When I have a class with file header, import statement and class documentation like this

/*
 * My file Header
 */

import javax.sql.DataSource

/**
 * Class Documentation
 */
class Dummy {
    DataSource ds
}

then "optimize imports" moves the import statement at the beginning of the file:

import javax.sql.DataSource

/*
* My file Header
*/

/**
 * Class Documentation
 */
class Dummy {
    DataSource ds
}

Is there a way to prevent this? I want the file header to be first in the file.
