Hello!

Yesterday I moved my SWT/JFace standalone Project from Eclipse 3.1M4 to
3.1M5a (WinXP SP2, Java 1.5).

I know that my application fails at a certain points and when I run the
application from Eclipse M4 and I reach such a point I get an Error
Message Box with the information "An error has occured. See error log
for more details."

In the console I can see for example the following exception message:

java.lang.IllegalArgumentException: Argument cannot be null

Running the same application from M5a, there is no message box and the
console shows me instead of the real exception:

Exception in thread "main" java.lang.NoSuchMethodError:
org.osgi.service.packageadmin.PackageAdmin.getBundle(Ljava/l ang/Class;)Lorg/osgi/framework/Bundle;
at
org.eclipse.core.internal.runtime.InternalPlatform.getBundle Id(InternalPlatform.java:307)

at .........


It's very annoying not to see the real exception. I think this is not a
SWT explizit problem. But perhaps can somebody tell me on which list I
should post the problem instead.

Thanks
Andreas Martin
