that your GLSL source has an error on line 0, column 12 ..
Should be easy to fix.

I merged a 'dualdepthpeeling' demo to jogl-demos:
<http://jogamp.org/git/?p=jogl-demos.git;a=commit;h=697d631bc0333b92689972ff3e621e3549fb6c80>
Then I JOGL'fyied it, ie. using our ShaderCode/Utils:
<http://jogamp.org/git/?p=jogl-demos.git;a=blob;f=src/demos/dualDepthPeeling/DualDepthPeeling.java;hb=HEAD#l431>
If using ShaderCode class, you can set the Java system property 'jogl.debug.GLSLCode'
which will dump the shader code w/ proper line numbers.
