Please provide a patch. How do you modify the shaders? According to the stack trace, the sprite batcher still uses the default shaders and your changes aren't taken into account. Moreover, which version of OpenGL or OpenGL ES do you target? If you target OpenGL 2.1, #version 120 makes sense; if you target OpenGL ES 2.0, it doesn't. Please ensure that you rebuild the JogAmp backend after making any change.
