Image transformation different in Labs 3 Final???

[spdaly]

I have a set of extensions running running on an Alf Labs 3.0b server.  One of the behaviors takes a JPEG content and converts it to a PNG content and creates a new node.  Works fine.

I'm testing 3.0 Final with the same code.  The transformation fails for some reason!  The "built in" transform action works on the same JPEG source when in the UI. 

I haven't changed anything in the code.  The 3.0 Final is straight from the install except for the extension code.  I have re-reviewed all the ImageMagick docs and nothing looks wrong.

Any help would be appreciated!

Here's the Java:

   private void doTransform(NodeRef nodeRef, ContentReader contentReader, ImageTransformationOptions imageOptions) {
      logger.debug("Create contentWriter");
      ContentWriter contentWriter = contentService.getWriter(nodeRef, ContentModel.TYPE_CONTENT, true);
      contentWriter.setMimetype(MimetypeMap.MIMETYPE_IMAGE_PNG);
      contentWriter.setEncoding("UTF-8");
      
       // try to pre-empt the lack of a transformer       
        if (contentService.isTransformable(contentReader, contentWriter, imageOptions) == false) {
            throw new NoTransformerException(contentReader.getMimetype(), contentWriter.getMimetype());
        }
        
      this.imageMagickContentTransformer.transform(contentReader, contentWriter, imageOptions);
   }

And the log message:

Have you created a rule for converting JPEG to PNG ?

Also make sure JPEG to PNG conversion should exists in Alfresco beans XML.

Are you running Alfresco in Windows or Linux???

I can't use a rule because of all the tasks that need to be completed.  I have written a behavior that works just fine in earlier 3.0 Labs builds.  It just stopped working in the 3.0 Stable build.
