native code crash in org.lwjgl.opengl.GL11.nglMultMatrixf

[anarchotron]

I just started using jwjgl so I am still learning my way around.  It looks pretty nice.

However I hit a native code crash tonight attempting to use the GL11.glMultMatrix(FloatBuffer) method.  My FloatBuffer is 16 elements long, and is rewound.

The native crash information is below.
Dunno if anyone can suggest anything so alleviate my pain, if not then just consider this a bug report, I suppose.

For what it's worth, I also get a crash in glLoadMatrix():

   at org.lwjgl.opengl.GL11.nglLoadMatrixf(Native Method)
   at org.lwjgl.opengl.GL11.glLoadMatrix(Unknown Source)

Ahh I figured it out after some  searching through the forums.  Apparently, FloatBuffer.allocate(16) does not return a valid float buffer but ByteBuffer.allocateDirect(16 * 4).asFloatBuffer() does!

[cfmdobbie]

Yes, float buffers must be direct, defined by the number of elements, and natively ordered.  To save yourself a lot of debugging, please use the BufferUtils utility class to create your buffers.

We are going to put in checks to ensure that all buffers passed to LWJGL are direct and throw an appropriate error message, I think, as this error turns up far too often as is a potential security hole.
