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...

Database Connection Pooling

I need to implement a simple connection pooling mechanism for my application. The problem is I have almost no knowledge working with database connections. What things should I take into account? Is there any lightweight library out there? I expect the code to open as few connections as possible.
