RFR: 6244047: impossible to specify directories to logging FileHandler unless they exist

[Jason Mehrens]

Jim,
 
You might just want to change the code to create and close a FileOutputStream in a way that doesn't truncate or damage the target file.  Or maybe use the NIO file code if that is possible.  See BUG ID 4420020.
