That sounds more like the texture data isn't uploaded rather than texture ids (just guessing). Anyway, I use this on Mac

final InputStream in = getClass().getResourceAsStream(resourcename);
final Texture tex = TextureIO.newTexture(in, false, "png");
tex.setTexParameteri(gl, GL.GL_TEXTURE_MAG_FILTER,
                GL.GL_LINEAR);
tex.setTexParameteri(gl, GL.GL_TEXTURE_MIN_FILTER,
                GL.GL_LINEAR);

then later on when rendering I do

tex.bind(gl);

to bind the texture when needed, that works fine for reading an image from file, so if that is your use case you could have a look at TextureIO
