File is a file in IFS.
Here is a more complete piece of code. The Java program reads a text file
from a directory and places is on a queue (MQ).
There is nothing to do with stdin, and sometimes it works.
This runs on a OS400 5.4 , JVM 1.4.

FileInputStream fstream = new FileInputStream(file);

if (fstream.available() > Integer.MAX_VALUE)
   System.out.println("File '" + file + "' is too big.");
int buffersize = fstream.available();
byte[] contents = new byte[buffersize];;

long n =, 0, buffersize);
fstream = null;
if (n != buffersize)
  System.out.println("Error in reading file '" + file + "'");
message = new String(contents);

What type of object is 'file' (the object you are passing to the
FileInputStream constructor.

Is it a file name, a File object, or a FileDescriptor object?

My gut says the file you are passing in to the FileInputStream
constructor is somehow the same as 'stdin', which is confusing java.
