TrueTypeFont problem

[h3xStream]

I'm trying to use TrueTypeFont like this tutorial suggest.

Rendering only the text is working fine. Including the drawing of a Quad, doesn't make any shape visible.
As soon as I comment the line [font = new TrueTypeFont(awtFont,true);], I can see the square as expect.

Init code

Code: Init

Display.setTitle(GAME_TITLE);
		Display.setFullscreen(fullscreen);
		Display.setDisplayMode(new DisplayMode(600, 400));
		
		// Enable vsync if we can (due to how OpenGL works, it cannot be
		// guarenteed to always work)
		Display.setVSyncEnabled(true);
		
		Display.create();
		
		width = Display.getDisplayMode().getWidth();
		height = Display.getDisplayMode().getHeight();
		
		GL11.glMatrixMode(GL11.GL_PROJECTION);
		GL11.glLoadIdentity();
		GL11.glOrtho(0, width, height, 0, -1, 1);
		GL11.glMatrixMode(GL11.GL_MODELVIEW);
		
		 //Font
		Font awtFont = new Font("Verdana", Font.BOLD, 20);
		font = new TrueTypeFont(awtFont,true);
		
		GL11.glEnable(GL11.GL_BLEND);
		GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
		
		
		//Background color
		GL11.glClearColor(1.0f, 1.0f, 1.0f, 0.0f);

Code: Render method

// clear the screen
		GL11.glClear(GL11.GL_COLOR_BUFFER_BIT | GL11.GL_STENCIL_BUFFER_BIT);
		
		//Text
		//font.drawString(10, height/2-20, "Hello World",Color.black);
		
		// rotate square according to angle
		GL11.glPushMatrix();
		GL11.glTranslatef(width / 2, height / 2, 0.0f);
		GL11.glRotatef(angle, 0, 0, 1.0f);
		
		GL11.glColor4f(0.0f, 1.0f, 0.0f, 0.5f);
		
		GL11.glBegin(GL11.GL_QUADS);
		{
			GL11.glVertex2i(-50, -50);
			GL11.glVertex2i(50, -50);
			GL11.glVertex2i(50, 50);
			GL11.glVertex2i(-50, 50);
		}
		GL11.glEnd();

		GL11.glPopMatrix();

The problem should be reproducible from this class alone, by commenting and uncommenting [font = new TrueTypeFont(awtFont,true);]
