Question about RandomAccessFile Code

Question about RandomAccessFile Code

[Patrick Ellis]

Mark/Tom,

During testing of the RandomAccessFile code, a file is create during execution called "raftmpfile". This
file is used during testing. 
My question is the code makes reference to the file twice in io/RandomAccessFile/jdk11.java but
raf2 is not used anywhere else in the code. A problem occurs on the VMS platform because of the
creation of the file twice in the below code. Was this the intent of the code or a bug ?  
        
        String fname = "raftmpfile";
        RandomAccessFile raf, raf2;
        int rdcnt;
        byte[] buf = { 0, 0, 0, 0 };

        // Start by deleting test file, if it exists,
        //      to clear out any leftover data

        File f = new File(fname);
        if (f.exists()) {
                f.delete();
        }

        // new RandomAccessFile(fname, mode)
    try {
        raf2 = new RandomAccessFile(f, "rw");
        }
        catch (IOException e) {
                harness.fail("new RandomAccessFile(File, mode): Can't open file " + fname);
                return;  // can't proceed without open file
        }

        // new RandomAccessFile(filename, mode);
        try {
        raf = new RandomAccessFile(fname, "rw");
        }
        catch (IOException e) {
                harness.fail("new RandomAccessFile(Filename, mode): Can't open file " + fname);
                return;  // can't proceed without open file
        }
        try {
                FileDescriptor fd = raf.getFD();
        }
        catch (IOException e) {
                harness.fail("getFD(): Can't get FileDescriptor");
                return;  // shouldn't proceed if no FileDescriptor
        }

I think the raf2 reference must be a residual of some code that I didn't
clean up well when I was in there last.  I've tested the code without it
and it seems okay.  I'll get it checked in shortly.
