Description Cherie Wong CLA 2004-05-25 11:07:16 EDT 
M9 GTK Build

I decided to do a "CVS Replace" on a project I had in my workspace.  It asked if
I wanted to overwrite my local changes.  I said "yes please!".  Then the error
below appeared 4 times in my Error Log... 

Everything still works but I'm not sure what this is :(

Comment 1 Kent Johnson CLA 2004-05-25 11:53:52 EDT 
From the stack trace, this is the call we are making in DiskIndex:

DataInputStream stream = new DataInputStream(new BufferedInputStream(new 
FileInputStream(getIndexFile())));

The constructor in BufferedInputStream is:

public BufferedInputStream(InputStream in) {
  this(in, defaultBufferSize);
}

which calls:

public BufferedInputStream(InputStream in, int size) {
  super(in);
  if (size <= 0) {
    throw new IllegalArgumentException("Buffer size <= 0");
  }
  buf = new byte[size];
}

We do NOT pass in the buffer size (we use the default) so how can it be <= 0?

Its initialized as:

    private static int defaultBufferSize = 2048;
