Trying to load a Font from resources throws a BufferUnderflowException

I am trying to load a Selawik font from my project's resources with following code:

try (InputStream is = getClass().getResourceAsStream("/fonts/selawk.ttf")) {
    Font selawik = Font.createFont(Font.TRUETYPE_FONT, is);
}

try (InputStream is = getClass().getResourceAsStream("/fonts/selawk.ttf")) {
    Font selawik = Font.createFont(Font.TRUETYPE_FONT, is);
}

but it results in an exception:

java.awt.FontFormatException: java.nio.BufferUnderflowException

Does anyone have any clue why? The font appears to be a valid TrueType font, but Java still refuses to load it...

The font was downloaded from here and it works okay, OS can load and use it I also tried to wrap my stream in BufferedInputStream, but with no effect AND the font loads just fine when I pass it as a File, but obviously I can't do that when it's inside a compiled jar file
