change may break source compatibility for client code that
uses one of the constructors expecting a password and passes
in null as password. We recommend to change the code to use a
constructor without password argument.

break code that relied on the finalizer to clean up an unfinished
stream. The code will need to be changed to call finish or

the feature was not 100% effective in any case.
