I can reproduce it now. Here is the start of the object tag that embeds Java:

<object classid="java:com.agfa.delano.applet.preload.Preload.class" type="application/x-java-applet" archive="applet-preload.jar,applet-streamproofnt.jar,applet-common.jar,httpclient.jar,commons-logging-signed.jar,commons-httpclient-signed.jar,commons-codec-signed.jar,streamproof_model-signed.jar,xbean-signed.jar,xmlbeans-qname-signed.jar,jsr173_1.0_api-signed.jar,apxproxy_model-signed.jar,ehcache-signed.jar,iText-signed.jar,iText-toolbox-signed.jar,bcmail-signed.jar,bcprov-signed.jar" width="100%" height="100%" id="PreloaderApplet">

Due to the non-empty classid, we immediately render fallback content. However, in this case there is a valid type attribute, and the classid attribute is clearly being co-opted to mean something other than "ActiveX/COM classid". We should probably relax our fallback rule to simply ignore non-empty classids (i.e. do not give them special meaning) rather than immediately rendering fallback content when we encounter one. If we were to do this here, we'd see a valid MIME type in the type attribute and successfully load the Java plug-in, passing the rest of the attributes as params to the plug-in.
