glGetUniformLocation issues

[ThorPrime]

Every time I try to call glGetUniformLocation, it throws the following error.

java.lang.IllegalStateException: Function is not supported
   at org.lwjgl.BufferChecks.checkFunctionAddress(BufferChecks.java:67)
   at org.lwjgl.opengl.GL20.glGetUniformLocation(GL20.java:470)
   at ShaderTest.initialize(ShaderTest.java:68)

I have tried creating the name byte buffer multiple ways (using BufferUtils, allocating a direct ByteBuffer) and it always returns the same result.

Is there something else I should be paying attention to?

(this is using lwjgl 1.0b3)

You graphics card doesn't seem to support glGetUniformLocation
