that takes like 2% of startup (not much but why is it done at all at this 
point?)

the culprit is Collator.getInstance, which is quite expensive (takes a second 
under a profiler)

Collator.getInstance has a cache. The first one to call it will pay the price 
for its instanciation. Is is called in many places in Eclipse. Optimizing it 
to not call getInstance will not optimize the startup since that time will 
show up in some other place.
