Well this mystery is not more of a mystery; because uDig is using the
same code (actually it uses GeoTools 2.2 - you could try your
application w/ GeoTools 2.2?)
Now that you have opened the file in uDig (which may be set up to use
more memory) try your application again ... now that the index file has been
created perhaps everything will be good? Also try IndexedShapefile and
non IndexedShapefile.
