Buggy source:
public void writeAdapter(ProcessingEnvironment processingEnvironment) throws IOException {
  TypeSpec.Builder typeBuilder=TypeSpec.classBuilder(adapterName).addModifiers(Modifier.PUBLIC,Modifier.FINAL).superclass(ParameterizedTypeName.get(ClassNames.MODEL_ADAPTER,elementClassName));

Fixed version (ground truth):

  TypeSpec.Builder typeBuilder=TypeSpec.classBuilder(adapterName).addModifiers(Modifier.PUBLIC,Modifier.FINAL).superclass(ParameterizedTypeName.get(ClassNames.MODEL_ADAPTER,elementClassName));
  InternalAdapterHelper.writeGetModelClass(typeBuilder,elementClassName);
  InternalAdapterHelper.writeGetTableName(typeBuilder,tableName);
  for (  MethodDefinition methodDefinition : methods) {
    MethodSpec spec=methodDefinition.getMethodSpec();
    if (spec != null) {
      typeBuilder.addMethod(spec);
    }
  }
  typeBuilder.addMethod(MethodSpec.methodBuilder("String_Node_Str").addAnnotation(Override.class).addModifiers(Modifier.PUBLIC,Modifier.FINAL).addStatement("String_Node_Str",elementClassName).returns(elementClassName).build());
  if (!updateConflictActionName.isEmpty()) {
    typeBuilder.addMethod(MethodSpec.methodBuilder("String_Node_Str").addAnnotation(Override.class).addModifiers(Modifier.PUBLIC,Modifier.FINAL).addStatement("String_Node_Str",ClassNames.CONFLICT_ACTION,updateConflictActionName).returns(ClassNames.CONFLICT_ACTION).build());
  }
  if (!insertConflictActionName.isEmpty()) {
    typeBuilder.addMethod(MethodSpec.methodBuilder("String_Node_Str").addAnnotation(Override.class).addModifiers(Modifier.PUBLIC,Modifier.FINAL).addStatement("String_Node_Str",ClassNames.CONFLICT_ACTION,insertConflictActionName).returns(ClassNames.CONFLICT_ACTION).build());
