You're in fact using a closure here so I'm not sure if that's causing issues.
Can you add following debug statements?
var r = new java.lang.Runnable() {
run: function() {
//add following print statements
print("fmt= " + fmt);
print("output_stream = " + ouput_stream);
// gives an exception here on the console
cocoon.processPipelineTo(fmt+"_pipe/"+url,{}, output_stream);
output_stream.close();
}
};

I changed the '' to {} like u said, not needed because when I dont use
the thread it works. Same with the pipelines, they work when I don't use
the thread (use_background_thread=false). I think I just need to be able
to set the environment (context?) inside the thread, check the
exceptions I get in the first message:
"org.apache.avalon.framework.context.ContextException: Unable to locate
object-model (No environment available)"
Relevant sitemap sections (which work when not using the thread):
<map:match pattern="pdf2_pipe/**">
<map:generate src="cocoon:/xsl-fo/{1}"/>
<map:serialize type="fo2pdf"/>
</map:match>
<map:match pattern="*.pdf2">
<map:call function="create_pdf">
<map:parameter name="report" value="{1}"/>
<map:parameter name="format" value="pdf2"/>
</map:call>
</map:match>
<map:match pattern="pdf2_display/**">
<map:read src="module:flow-attribute:file_name"
mime-type="application/pdf" />
</map:match>
