Seems like the work in
GRECLIPSE-1233 is not complete. Mark occurrences is not correct when there are default parameter references coming from other files. Eg-
and in another file:
Select the first, third or fourth method reference and the first, third, and fourth reference highlights. Select the second, and only the second highlights.
The correct behavior is that selecting any method reference should select all other references. This is the behavior that you see when all are inside the same file.
