URL stream breaks on reading

Question

Okay, I have a routine that works perfectly! Until a file is a certain size. I know it works on files that are 4k but not on 10k.
What happens is it fetches the first part of the file and then just blocks (which it is supposed to until the file comes across, but it never does). It's like the stream breaks or something.
        URLConnection connection = contentURL.openConnection();
        byte[] data = new byte[ connection.getContentLength() ];
        InputStream istream = connection.getInputStream();
        while ( istream.available() < connection.getContentLength() ) {
            try {
                wait( 10 );
            } catch ( Exception e ) {}
        istream.read( data );
        istream.close();If anyone has code to fetch a file via URL I be grateful for help. This is a critcial part of my project and I'd like to be able to use files greater than about 4k.
Thanks a ton.

Sounds like there is a buffer of 4K. Just read whenever there is something to read:
URLConnection connection = contentURL.openConnection();
byte[] data = new byte[ connection.getContentLength() ];
InputStream istream = connection.getInputStream();
int offset = 0;
int read;
while ((read = istream.read(data, offset, data.length-offset)) != -1 && offset < data.length) {
  offset += read;
istream.close();
// the last part should not occur, just to verify it worked
if (read != -1 || offset != data.length)
  System.out.println("Something went wrong");
