Hi @asomov ! I know this is quite an obscure thing, but may be worth handling. Issue found by OSS-Fuzz via Jackson YAML module. Let me know if you need more information (or if you'd like me to file an issue in snakeyaml bug tracker).

I did not quite catch what is the YAML which fails

Sorry ! I see the test. I will check it.
