This PR replaces the use of
tap()
withtry...finally
in theNumber::withLocale()
andNumber::withCurrency()
methods to ensure that the previous static state is always restored, even if the callback throws an exception.Currently, if an exception is thrown inside the callback passed to
withLocale()
orwithCurrency()
, the previous locale or currency is not restored. This can lead to inconsistent formatting behavior in subsequent operations.
