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)
