Agreed, a shader program shall not crash the process
regardless of erroneous GL commands ..

You can try setting the debug properties:

-Djogl.debug.TraceGL
  trace all GL commands

-Djogl.debug.DebugGL
  exception if GL command fails, also enables the debug extension if available

-Djogl.debug.GLSLCode
  if using our com.jogamp.opengl.util.glsl.ShaderCode,
  this will dump the shader _and_ any compile/linkage problems.
  see our GL2ES2 demos / unit-tests
