Description Jared Burns CLA 2001-10-10 22:18:58 EDT 
public class Hello() {

	public static void main(String[] args) {
		int x= 255
		int y= 67;
		System.out.println("Hello, World!");
	}

}

1. Turn on the "Display ASCII values" preference.
2. Place a breakpoint on line 6 ("System.out") and debug Hello
3. Note that x's label is completely empty in the variables view

I've debugged this enough to see that the JDIModelPresentation *is*
generating and returning the correct label for x.

NOTES:
Comment 1 Darin Wright CLA 2001-10-15 11:51:36 EDT 
If we are generating the correct label, why is it not displaying?
Comment 2 Jared Burns CLA 2001-10-15 18:10:36 EDT 
This bug is actually much worse than I thought. It's not at all related to the
ASCII display preference.
We completely bomb when trying to display any string that contains a char > 127.
This bug is new to the 2.0 stream.

public class Hello() {
	public static void main(String[] args) {
		char c= (char) 255;
		System.out.println("Hello, world!"); // breakpoint here
	}
}
Comment 3 Jared Burns CLA 2001-10-17 15:02:37 EDT 
Appears to be a Linux-only SWT or UI bug.

PRODUCT VERSION:
2.0 stream
Comment 5 Grant Gayed CLA 2001-10-24 11:44:08 EDT 
Fixed by Silenio.  We now use memmove to ensure that the bytes are moved in the 
correct order according to the endianness of the platform.

This introduces a limitation on RedHat 6.2, which is fine since this is not a 
2.0-supported platform.  This has been documented in the swt readme (99.1.11 
Non ASCII strings on Linux).
