I'm using .png with alpha-channel myself and everything works fine here.

To load the texture I use:

Texture tTexture = TextureIO.newTexture(new BufferedInputStream((new Object()).getClass().getResourceAsStream(inFileName)),true,null);

And the blending mode is:

inGL.glEnable(GL_BLEND);
inGL.glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_COLOR);
