For the GL query, use Julien's above.

Here you can see how you gather all available GLCapabilities:
  http://jogamp.org/git/?p=jogl.git;a=blob;f=src/test/com/jogamp/opengl/test/junit/jogl/acore/TestGLProfile01NEWT.java;hb=HEAD#l58

Here is a test whether a list of such caps has any multisample support in it:
  http://jogamp.org/git/?p=jogl.git;a=blob;f=src/test/com/jogamp/opengl/test/junit/jogl/caps/MultisampleChooser01.java;hb=HEAD

Applied here for one NEWT window's GLDrawable
  http://jogamp.org/git/?p=jogl.git;a=blob;f=src/test/com/jogamp/opengl/test/junit/jogl/caps/TestMultisampleNEWT.java;hb=HEAD

.. but you can check on all available caps (see above) as well.
