Yaml.createYamlDump(Enum).dump().toString() produces StackOverflowError

[CuteLuoBo]

After passing the enumeration class into the Yaml.createYamlDump(Object).dump() method, calling YamlNode.toString() will cause a StackOverflowError

Usage version

eo-yaml 7.0.9
jdk 11

How i found out

My JavaBean contains enumeration properties. When I directly call this method to get the YamlNode, this error occurred. After troubleshooting, I finally found out that the problem was caused by the enumeration passed in. Currently I solved it by implementing additional logic.

How to reproduce

@Test
   public void debug() {
       YamlNode node = Yaml.createYamlDump(TimeUnit.DAYS).dump();
        System.out.println(node);
    }
