A DESCRIPTION OF THE PROBLEM :
The FileOutputStream constructor is throwing a FileNotFoundExeception when "long" paths or filenames are used.  We have noticed slightly different behavior depending on the exact nature of the file/path.

For just file name (no path), the file name must be very long (~200 characters).

For relative paths, the path needs to be fairly long, but no individual path component or file name is unusually long.

For absolute paths, the exception is not thrown, but the file is not created.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached code.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The FileOutputStream should be created without error and the file should exist.
ACTUAL -
The FileOutputStream constructor throws an exception. With an absolute path, the constructor succeeds, but the file does not exist.
