Changes requested by aivanov (Reviewer). src/java.desktop/windows/classes/sun/awt/windows/ThemeReader.java line 117: > 115: if (theme == null || theme == 0) { > 116: theme = openTheme(widget, defaultDPI); > 117: } `theme` can't be `null` because `openTheme` returns `long`. Perhaps, the declaration should be changed to long theme; This is still incorrect. If `i > 0`, there's a prerequisite to calling `openTheme`. Likely, you need another helper method. ------------- PR Review: https://git.openjdk.org/jdk/pull/18706#pullrequestreview-2015052771 PR Review Comment: https://git.openjdk.org/jdk/pull/18706#discussion_r1574925429
