Re: java 1.1.7/Linux Thread switching
My thanks to everyone for the replies about thread interleaving. The other thing I'm still trying to sort out is this issue with native threads in jdk 1.1.7v3 and redhat 6.0 (with glibc 2.1). There seems to be a library mismatch or something. A simple threaded program runs fine with native threads on a system with glibc 2.0.7 but doesn't work reasonable at all with glibc 2.1.1. Are there any known conflicts, and if so are there any known work-arounds? Of course, it might be something other than glibc that's conflicting... the symptom I see is that a Thread.sleep(1l) returns much, much sooner than it should with no error thrown. I can supply a program to demonstrate the problem if anyone wants. thanks again, Rich [EMAIL PROTECTED] The native threads implementation is just plain broken on glibc-2.1 systems.

Re: Version snag
Not all in this group.
Since you ported Java stuff to pre2, this is the place to
go lookin for answers.
If people drag you down, the energy wasted is theirs.

[Q] Displaying large image with MemoryImageSource
Hi everybody, I had problems displaying a large image constructed from a
big buffer of int's using MemoryImageSource. The maximum size it can
display seems to be about 600x500. Anything bigger than that will just
give me a white window. I checked the buffer and is very sure that
there's valid data inside and also had tested it under Window95 and NT.
It works fine under the Windows.
The following is the code that I use: (buffer is about 1700x1200)
(Problem arises when width and height is over 600)
public construct_image() {
Constructing buffer and setting its values here.
..
image = createImage
(new MemoryImageSource
(width, height, buffer,
0, width));
.
}
public void paint (Graphics g) {
setBackground(Color.blue);
g.drawImage(image, 0, 0, this);
}
Any suggestions is greatly appreciated.
