Texture different in mac and linux

Hello. I'm struggling with my textures and I would really appreciate some help.
I have a piece of code which renders a texture from a jpg file. The code gives different result for Linux and Mac and I can't understand if I am the cause for the problem (probably yes). On both machines I'm using Java 7 and the latest jogl libraries (since December 2013).
The code is giving me the results that I want on the Linux Machine. On the Mac, however, if the animator is running the image shows for a second and then it shrinks to an invisible size. If I don't start the animator the image stays but is smaller that the square that I'm trying to map it onto. I am inerting screenshots of what the results look like.
I am also attaching my code (and the 2 shaders). I think it's simple enough. The java class is  justTexture.java, the vertex shader colorTexture.vert and the fragment shader colorTexture.frag.
I suspect that maybe I'm doing something wrong when I activate and bind the texture or when I send the sampler2D location to the shader.
This is where I initializa the texture
texture = TextureIO.newTexture(new File("Varna.jpg"), false);
                byte[] buf = new byte[texture.getWidth()*texture.getHeight()*4];
                ByteBuffer buffer = ByteBuffer.wrap(buf);
                gl.glGenTextures(1, textureId, 0);  
                gl.glActiveTexture(GL3.GL_TEXTURE0);
                gl.glBindTexture(GL3.GL_TEXTURE_2D, textureId[0]);  

                gl.glTexImage2D(GL3.GL_TEXTURE_2D, 0, GL3.GL_RGBA, texture.getWidth(), texture.getHeight(), 0, GL3.GL_RGBA, GL3.GL_UNSIGNED_BYTE, buffer);
                texture.setTexParameteri(gl, GL3.GL_TEXTURE_MIN_FILTER, GL3.GL_LINEAR);
                texture.setTexParameteri(gl, GL3.GL_TEXTURE_MAG_FILTER, GL3.GL_LINEAR);

then I create a location for the sampler
         iSampler = gl.glGetUniformLocation(iTexProgram, "Tex1");

and the code below goes in the display function
        gl.glUseProgram(iTexProgram);
        gl.glUniformMatrix4fv(iTexMVP, 1, false, texMVP, 0);
        gl.glUniform1i(iSampler, 0);
        gl.glBindVertexArray(iVao[0]);
        gl.glDrawArrays(GL3.GL_TRIANGLES, 0, 6);
        gl.glBindVertexArray(0);

Thank you in advance for your help. I really appreciate it.

Hi

This has nothing to do with the operating system. One of your graphics cards (under Mac) doesn't support non power of two textures.

Edit.: Please use at least JOGL 2.1.4 before investigating further.

Thank you for the response gouessej. I updated my jogl (I didn't realize there was an even newer release than December) and I made my picture 256x256. That gave me the same results.
However, I switched back to Java 6 and now it's working just the way I want it to :)

I don't understand why switching to Java 1.6 solved your problem :s

Edit.: Use NEWT instead of Swing and AWT. Maybe there is a bug in Oracle Java 1.7 that affects heavyweight / lightweight mixing.

I am confused too.
Thanks for the suggestion to use NEWT. I will try it next week and will post again with the results.

Hi i uploaded your example to
https://github.com/xranby/jogamp-forum-examples/tree/master/Lili/justTexture

git clone https://github.com/xranby/jogamp-forum-examples
cd jogamp-forum-examples/Lili/justTexture
./fetch-jogamp-build.sh
./run.sh

Since i did not have access to your Varna.jpg image i added one i found on the internet that was free for use on desktop systems.
It work on my linux system.

I added an AWT -> NEWT port of your example that you can try

gouessej and Xerxes Rånby, thank you both so much for you help. NEWT seems to have solved all my problems on both Linux and Mac using Java 1.7
