> There is a reproducible bug in symbol rendering on Windows machines with [particular](https://github.com/openjdk/jdk/blob/9d71af108ea2cc3682607527246d60a19fd820ba/src/java.desktop/windows/native/libawt/windows/awt_Win32GraphicsEnv.cpp#L244) default locales. This changeset fixes the deferred font initialisation request, which now skips the last font in the list.
>
> The test (attached to the jira) was performed on a Windows 11 machine with the Japanese locale set as the default. Without the fix, it fails with an NPE. With the fix it displays a window showing glyphs drawn by all the fonts accessible from the Java application.
