Find usages broken in 3370?

Doing "find usages" on a method from an interface in 3370 by right-clicking
on one of the places that the method was actually used returns no results
for me. Note that, because our project structure is broken, we do not have
our EJBs set up correctly (they're in a monolithic source tree); the method
in question is an EJB method and no class actually implements it, but before
3368, searching for such usages worked fine. Is anyone else seeing problems
like this?
