As mentioned above, FormEditorSupport.JavaEditorTopComponent.getToolbarRepresentation() waits for editor pane to be initialized. But how else it should get the toolbar?

The code is:

JEditorPane pane = getEditorPane();
if (pane != null) {
    Document doc = pane.getDocument();
    if (doc instanceof NbDocument.CustomToolbar) {
        toolbar = ((NbDocument.CustomToolbar)doc).createToolbar(pane);
    }
}

It's the CloneableEditor.getEditorPane() that is slow, yet requires to be called in EDT. I don't see what could be done with this on GUI builder side, if anybody knows please let me know. Is there a way to get to the document/toolbar out of EDT?
