"libjawt.so" not loaded by Java 7

[Kapta Ulo]

Thanks for clearing that up, much appreciated.
It seems that LWJGL was relying on java.awt.Toolkit.getDefaultToolkit(); to load libjawt.so, which had worked fine but is no longer the behaviour with Java 7.

The fix/solution to the problem was to just manually load libjawt.so using System.loadLibrary("jawt");
Thanks
Kapta

The project has been calling the following method: java.awt.Toolkit.getDefaultToolkit(); to ensure that this native file is loaded, this has worked fine for the last 6 or so years. There seems to have been some internal change which causes this to break. Any idea's on what it could be and how to fix this?
