With glGenBuffers it's working to create the buffers but later i got an exception at
ByteBuffer globalMatricesPointer = gl.glMapNamedBufferRange(this.bufferName.get(Buffer.GLOBAL_MATRICES), 0,
                                16 * 4 * 2,
                                GL_MAP_WRITE_BIT | GL_MAP_PERSISTENT_BIT | GL_MAP_COHERENT_BIT | GL_MAP_INVALIDATE_BUFFER_BIT); //

By the way my video board supports OpenGL 4.0.0
GL_RENDERER    Intel(R) HD Graphics 4000
GL_VERSION     4.0.0 - Build 10.18.10.4358
