How to fix sealing violation from a library? sealing violation: package org.lwjgl.opengl is sealed
<p>While setting up a project as a template for Slick2d based projects following the instructions here:<a href="http://slick.ninjacave.com/wiki/index.php?title=Setting_up_Slick2D_with_Eclipse" rel="nofollow">Slick2d wiki</a> using the provided code for testing setup <a href="http://slick.ninjacave.com/wiki/index.php?title=Hello_World" rel="nofollow">here</a> at run-time I keep getting a giant block of sealing errors. My thought is that this problem stems from the version of ljgwl.jar in both libraries, however Slick requires both in order to function properly. How can I resolve this?</p>
