I think this has already been fixed, quite recently, indeed as a
minor supporting part of 

    commit 92c56300c317c9e5573dca787a2cf20f777b3179

        CC Mode: Optimize for scrolling large buffers containing few braces

The fix had been in standalone CC Mode for a few years, but somehow
evaded getting merged to savannah.  The above commit hit merge conflicts
around the area, and adding in the fix to the Java annotations fixed
those conflicts at the same time.

So, could I ask you to try out the bug scenario again, notice that it is
now fixed, and close the bug.

Thanks!
