Description

If an object defines getProperties(), JsonOutput.toJson(def) fails with the following:

groovy.lang.MissingMethodException: No signature of method: com.foo.FileProperties.remove() is applicable for argument types: (java.lang.String) values: [class]
Possible solutions: getAt(java.lang.String)
...
	at groovy.json.JsonOutput.toJson(JsonOutput.groovy:131)
...

Repro:

class MyClass { String properties }
groovy.json.JsonOutput.toJson(new MyClass(properties: 'properties'))
