The output of getMessage isn't that simple to interpret. Here it is filename+" (Too many files open)",
and on other platforms it is probably something else. This goes for the message part of most exceptions
thrown from platform specific code like file i/o socket i/o etc. The type of exception is a FileNotFoundException,
btw.
I wonder whether your code works on any platform.
