[tor-commits] [metrics-lib/master] Avoid static initializer blocks.

commit cbda9efad1f5a514fcd62378013431b20b2f9fd8

    Avoid static initializer blocks.
    
    Commit 1bf8a7f introduced a problem with parsing perfectly valid date
    strings.  Changing the SimpleDateFormat class member to a local variable
    and avoiding its initialization in a static initializer block solved the
    problem.  It's unclear what exactly the problem was, possibly related to
    class loader weirdness.  Using a local variable fixed it.  Wasted enough
    time on this problem.
