SWT scale slider sometimes not functional on Windows [message #313001]

In WTP, we use a org.eclipse.swt.widgets.Scale object in our wizard. I
found that some of the time (usually after 1 or 2 scenarios or sometimes
even just after the workbench is loaded), the scale slider graphic cannot be
displayed properly and instead, a red square is displayed for the scale and
for the background. When that happened, I could not even move the scale at
all to adjust the level. I found this problem when running code on Eclipse
3.2.2 or Eclipse 3.3 M5. I have run into this using JDK 1.4.2 and JDK 1.5.
The problem only occurs on Windows but not Linux.

I've attach the following:

- client_Page1.png - the page without scale loading problem
- client_Page1Error.png - the page with scale loading problem
- scale3_background.png - the background used behind the scale

Is there any tracing I could do to isolate the problem?

This turns out to be a problem with Plugin.getBundle() when different
bundles use the same activator class. Please refer to bug 175476
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=175476) for more detail.
