java - lwjgl freezes on creation of Font object -

i making simple game of snake, because can, , stumbled across interesting bug. trying use slick-util draw text on screen, whenever try create font object game freezes. here code. highlighted section prints 'a' once.

any ideas?
thanks,

have tried font "arial" or "serif"? guess "default" not valid name font in windows.

try this:

font awtfont = new font("times new roman", font.bold, 24); font = new truetypefont(awtfont, false); 

or, if have .ttf file try this:

try {     inputstream inputstream = resourceloader.getresourceasstream("anotherfont.ttf");     font awtfont = font.createfont(font.truetype_font, inputstream);     awtfont = awtfont2.derivefont(24f);     font = new truetypefont(awtfont2, false);       } catch (exception e) {     e.printstacktrace(); }
