[JSch-users] dead lock during large file transfers

[Filip H. <fi...@ha...>]

Hi there,
we are constantly getting dead locks while doing large file transfers from
one system to another.

I believe the problem might be in the use of the Piped streams and the fact
that IO is blocking.
I added in the following check to IO.getByte and it seems as it is working
fine.
Would this cause any other problems, or is the while loop acceptable as a
bug fix?

void getByte(byte[] array, int begin, int length) throws IOException {
    do{
      while ( in.available() <= 0 ) {
        try {
          Thread.sleep(10);
        } catch ( java.lang.InterruptedException x ) {
          x.printStackTrace();
          break;
        }
      }
      int completed = in.read(array, begin, length);
      if(completed<=0){
	throw new IOException("");
      }
      begin+=completed;
      length-=completed;
    }
    while (length>0);
  }
