[Ikvm-developers] IKVM can not cast sun.awt.image.ToolkitImage to java.awt-image.BufferedImage

[Vito S. <vit...@gm...>]

Apologies first, if this is the wrong place to ask for help (redirect me
pls, if this is so).

I have been looking for possible causes of the problem below quite
extensively, but the few cases, where "ClassCastException: *sun*.*awt*.*
image*.*ToolkitImage* *cannot be cast to ..."* was mentioned, were not
helpful insofar code changes have been suggested - and I have an inkling,
the problem should be simpler to solve.

I am trying to run ImageJ (http://rsbweb.nih.gov/ij/)  using ikvm and I get
the following exception and post-mortem:

*D:\Data\ikVlll-7.0.4H5.0\bin>ikvm -jar ij.jar
Exception in thread "main" java.lang.ClassCastException: Das Objekt des Typs
sun.awt.image.ToolkitImage kann nicht 1n Typ java.awt.image.BufferedImage
umgewandelt werden.

The IKVM version is as follows:

I have an identical problem with another ikvm version (0.46.01) and OpenJDK
version (OpenJDK 6 b22). I used ikvmc in this environment to create
ij.dll. It behaves decently in my environment (.net 4,  Visual Studio 2010,
c#)  except when it comes to creating the GUI - nothing going on. I added
IKVM.OpenJDK.SwingAWT assembly to references (to silence some "unsatisfied"
grumbles;) , on top of IKVM.OpenJDK.Core and IKVM.RunTime. Am I missing
something evident here?

Please let me know, what else you would need to know to make any
suggestions.

Using Eclipse on the Java side and as already mentioned Visual Studio and
C# on the .NET side.

Sincere regards
