Nicolas Spiegelberg commented on HBASE-4783:
--------------------------------------------
@Ted: Can change this for readability on commit. This shouldn't matter for
performance. The compiler should optimize this outside the loop since it is
final. Even if not, the string will be cached in the static string space of
the class file and this should just amount to setting a register address each
time.
Any other +1 blockers?
