i would replace:
   JSObject result = (JSObject) 
webEngine().executeScript(String.format("convertDocbook(editorValue,docbookOptions)"));
     return ....

with:



CompletableFuture<JSObject> future = CompletableFuture.supplyAsync(
() -> {
       return
(JSObject) 
webEngine().executeScript(String.format("convertDocbook(editorValue,docbookOptions)"));
}
);


    return new ConverterResult(future); <<< you should check if future is 
present

change your method an provide a consumer to call on completion an do not 
return the result (would be better)
