There is no text on Labels and Buttons using swt-win32-3139.dll in the
directory C:\x86 when I run in stand-alone mode as in the ant script
below. This runs Snippet108 to display a very simple form. That code is
below as well. An interesting note is that if I leave the application
running, something triggers a re-draw and the text gets displayed.


<path id="my.class.path">
<pathelement path="build"/>
<pathelement
location="C:/x86/org.eclipse.swt.win32.win32.x86_3.1.1.jar"/ >
</path>

<target name="x" depends="compile"
description="run the application" >
<java dir="build"
fork="true"
classname="org.eclipse.swt.snippets.Snippet108" >
<jvmarg value="-Djava.library.path=C:\x86"/>
<classpath refid="my.class.path">
</classpath>
</java>
</target>


SNIPPET..............

People have reported an issue like this when running with java.exe which
gets fixed by running with javaw.exe. I have never seen this problem myself
and I run with both regularly.

What VM are you using? Can you try a different one?

Here is the command I run and get no Text on labels and buttons:

"C:\Program Files\Java\jre1.5.0_06\bin\javaw.exe"
-Djava.library.path=C:\x86


If I change javaw to java I get the text again.

Here is the version information:

java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)

In my previous post I said I changed javaw to java and it worked, but
actually it was the reverse. I changed java to javaw. One thing that
this implies is that I can't use the java 'ant task' to test. I probably
have to set up and ant task to spawn javaw instead.

This seems like a serious problem to me even if there is an easy fix. Is
there any work being done to find out what's happening here? Is there an
open bug report?
