Robert Muir updated LUCENE-2791:
--------------------------------

    Attachment: LUCENE-2791.patch

i turned mike's benchmark into a unit test, and toned it down a bit.

so i agree with uwe on only one thing, and thats optimizing the case where we 
throw an exception.

but i disagree on the other things: i think we should just have language 
neutral error messages and ascii-only files as i presented here... this isn't 
for general purpose use: its just for lucene. there is no need to bring wchar, 
etc into this.

so, since all tests pass and this fixes the bug in SimpleFS, i will commit to 
contrib/misc coon.
