System: Linux isabella 2.4.18-4GB #1 Wed Mar 27 13:57:05 UTC 2002 i586 unknown
Architecture: i586

	
host: i586-pc-linux-gnu

>Description:
I tracked down the reason, why java.io.StreamTokenizer can't parse
numbers any longer. The testcase is narrowed from
java.lang.Character.isWhitespace, which is returning true on digits
because of this bug.

I consider this to be of high priority.
>How-To-Repeat:
# gcj -g --main=HelloWorld HelloWorld.java
# ./a.out 
this should be false: true

public class HelloWorld {

    static int attr = 0x9;

    public static void main(String [] args) {
	boolean res = ( ( 1 << attr ) & 0x1000 ) != 0	;
     	System.out.println("this should be "+res+": "+isWhite());
    }

    public static boolean isWhite() {
	return ( ( 1 << attr ) & 0x1000 ) != 0 ;
    }

}
