Output:

fmt= pdf2
output_stream = com.spectron.io.fileprogressoutputstr...@fc8361

I know that part works (i can access objects variables in thread) because I tested it with something like this:

var length=0;
var r = new java.lang.Runnable() {
    run: function() {
        while(true) length++;
    }
};
new java.lang.Thread(r).start();
// Display the waiting page until complete:
while(!output_stream.isClosed()) {
  cocoon.sendPageAndWait("progress.jx",{ "length" : length });
}

And the progress page displayed the length variable, and it was increasing (the thread was working). The problem seems to be that inside the thread none of the cocoon-related objects can be used.

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();
     }
};
