Jeff McAffer suggested that I make the
PMC aware of Bug 191224 - Binary compatibility breakage: API method removed
from IIndexEntry. There is a discussion in the bug of whether it
is better to live with the binary incompatibility or try to revert the
API. Please add a comment to the bug if you have an optinion https://bugs.eclipse.org/bugs/show_bug.cgi?id=191224.
