Confirmed. The XMas patch fixes the InputStream.available() bug.

Subject: [Kaffe] bug in InputStream.available() method

Here is a simple "echo" type of program that fails under
kaffe (off a fresh CVS tree). The System.in.available()
method seems to be returning -1 when there are 0 bytes
available. This same code works just find under a Sun JDK.
I was running under solaris-sparc2.6 and I compiled with gcc.

public class echo {
    public static void main(String[] argv) throws Exception {
	System.out.println("Please begin typing");
	while (true) {

	    int avail = System.in.available();

	    if (avail == 0) {
	    } else {
		byte[] buff = new byte[avail];
		//echo back what was just typed
		System.out.println("-----ECHO BEGIN-----");
		System.out.println("-----ECHO END-----");
