I assume that he meant that glBlendFunci is only in GL4 despite the documentation that mentions it in GL2GL3. I've just tested with an old version of JOGL and only GL4.glBlendFunci compiles, not GL2GL3.glBlendFunci.

He can safely use it if his hardware supports OpenGL 4, otherwise he should check if one of the extensions is available.
