Fixed version (ground truth):
private CourseEditInstructorPanel createInstructorPanel(int instructorIndex,InstructorAttributes instructor,List<String> sectionNames,List<String> feedbackNames){
  CourseEditInstructorPanel instructorPanel=new CourseEditInstructorPanel(instructorToShowIndex,instructorIndex,instructor,sectionNames,feedbackNames);
  if (instructor != null) {
    String buttonContent="String_Node_Str";
    boolean isDisabled=!currentInstructor.isAllowedForPrivilege(Const.ParamsNames.INSTRUCTOR_PERMISSION_MODIFY_INSTRUCTOR);
    String href;
    String onClick;
    if (instructor.googleId == null) {
      href=getInstructorCourseInstructorRemindLink(instructor.courseId,instructor.email);
      onClick="String_Node_Str" + instructor.courseId + "String_Node_Str"+ instructor.email+ "String_Node_Str";
      instructorPanel.setResendInviteButton(createButton(buttonContent,"String_Node_Str","String_Node_Str" + instructorPanel.getIndex(),href,Const.Tooltips.COURSE_INSTRUCTOR_REMIND,onClick,isDisabled));
    }
    buttonContent="String_Node_Str";
    instructorPanel.setEditButton(createButton(buttonContent,"String_Node_Str","String_Node_Str" + instructorPanel.getIndex(),"String_Node_Str",Const.Tooltips.COURSE_INSTRUCTOR_EDIT,null,isDisabled));
    buttonContent="String_Node_Str";
    href=getInstructorCourseInstructorDeleteLink(instructor.courseId,instructor.email);
    onClick="String_Node_Str" + instructor.courseId + "String_Node_Str"+ instructor.email+ "String_Node_Str"+ instructor.email.equals(this.account.email)+ "String_Node_Str";
    instructorPanel.setDeleteButton(createButton(buttonContent,"String_Node_Str","String_Node_Str" + instructorPanel.getIndex(),href,Const.Tooltips.COURSE_INSTRUCTOR_DELETE,onClick,isDisabled));
  }
  return instructorPanel;
