I entered a bug report at
  https://jogamp.org/bugzilla/show_bug.cgi?id=874

Sorry I spent one day trying to fix this issue myself and I failed to resolve the issue. I am unable to give this more attention in the near future, so I explained what I learned in that issue report, and hopefully someone can carry this further in the future.

In the meantime, I am working around this issue in my own applications by manually applying sRGB color correction as the very last step of my GLSL fragment shaders. Just as GL_FRAMEBUFFER_SRGB was expected to do automatically.
