On Cent OS 5.3, I do this:
// get the profile
GLProfile profile = GLProfile.getDefault();
// this allows us to set particular properties for the GLCanvas
GLCapabilities glCapabilities = new GLCapabilities(profile);

...

final GL2 gl = GLContext.getCurrentGL().getGL2();
final GL2ES1 gl2es1 = GLContext.getCurrentGL().getGL2ES1();

and it works fine, gl2es1 is not null. I use the latest build.
