Concurrency Problem in BeanFactoryTypeConverter [INT-2889]

[spring-operator]

Gary Russell opened INT-2889 and commented

Consider a transformer:

public String transform(String payload, @Header("id") String uuid) {
...
}

The 'id' header is converted from UUID to String; however, the BeanFactoryTypeConverter is not thread-safe...

editor.setValue(value);
String text = editor.getAsText();

So, concurrent messages can get the value of some-other conversion.
