To nest a SAR project or an ESB project inside a EAR and have it be recognized as a child project, a nasty inefficient workaround needed to be used. With the introduction of the upsteam GlobalHeirarchyParticipant and a global list to register yourself in, this wasteful workaround is no longer necessary.

Remove it.

To test:

1) verify esb project and sar project can nest inside ear and be published correctly
2) verify esb and sar project can have a Utility Project nested inside and be published correctly.
