Hi. Japanese document class (e.g. ltjsarticle) reported error in this document like https://tex.stackexchange.com/questions/222320/russian-in-document-with-japanese-as-main-language-lualatex-ltjsarticle or generating PDF with Pandoc from Markdown document. ("pandoc --pdf-engine=lualatex -V documentclass=ltjsarticle document.md -o document.pdf")
Then reported this error.
```

ltj@@jfont ->luafunction ltj@@jfont@inner
