Isn't it mentioned anywhere ? Please file a bug on documentation; I will
try to document the cookies injected by java project support to various
places - if my time permits (or does someone want to document it sooner
?)

Every SourceElement extracted from a project-aware context should have
such cookie (to provide exactly the binding to the project you seem to
need). Those created directly on top of a file
(DataObject.getCookie(SourceCookie.class) are not bound to any project -
DataObject is project-neutral.

It should be a part of Java Project API contract, however, that there's
a ProjectMember in the lookup of source / class / method. 
Although for a few carefully selected things, natural for the model it
is OK to have direct getters, I do not know if the Project/ProjectMember
is the case -- what others think ?
