Eks Dev commented on LUCENE-1345:
---------------------------------
bq. comparison with -1 is being optimized away entirely
I do not think so, how compiler could "optimize away" the only condition that
stops the loop? The loop would never finish, or am I misreading something here?
Anyhow, the test is so simple that compiler can take completely other direction
from the real case. I guess much better test (without too much effort!) would
be to take something like OpenBitSetIterator and make one Iterator
implementation with sentinel approach and then compare... this test is really
just a dumb loop, but on the other side isolates the difference between two
approaches...
