Here is the new comment for loadAssistiveTechnologies for review:
/**
* Loads accessibility support using the property
assistive_technologies.
* The form is assistive_technologies= followed by a comma-separated
list of
* assistive technology providers to load. The order in which
providers are
* loaded is determined by the order in which the ServiceLoader
discovers
* implementations of the AccessibilityProvider interface, not by
the order
* of provider names in the property list. When a provider is found its
* accessibility implementation will be started by calling the
provider's
* activate method. All errors are handled via an AWTError exception.
*
* The assumption is made that assistive technology providers are
supplied
* as part of java.desktop module or specified on the classpath.
