After code clean up done in JDK-8223586 logic of some code was altered unexpectedly.

E.g.: rename of parameter from "p" to "params" in WindowsAppImageBuilder.createLauncherForEntryPoint():
---
private void createLauncherForEntryPoint(
            Map<String, ? super Object> params) throws IOException {
        File launcherIcon = ICON_ICO.fetchFrom(params);
        File icon = launcherIcon != null ?
                launcherIcon : ICON_ICO.fetchFrom(params);
...
}
---

Used to be before renaming:
---
private void createLauncherForEntryPoint(
            Map<String, ? super Object> p) throws IOException {
        File launcherIcon = ICON_ICO.fetchFrom(p);
        File icon = launcherIcon != null ?
                launcherIcon : ICON_ICO.fetchFrom(params);
...
}
---

"params" parameter shadows WindowsAppImageBuilder.params member field.

I've discovered this issue accidentally. Probably there are more like this.
