Springjpa and thymeleaf work together, the two classes cascade reference each other, HTML pages use objects, error report, is the bug of thymeleaf?

https://github.com/thymeleaf/.

I use jpa, to cascade the two classes through annotations.
in the html page, when you get the object of any class through the thymeleaf tag, it will appear

.

this error, this should be the bug of thymeleaf. Did thymeleaf fix this bug?
my solution now is to use the third-party json jar package jackson to convert the object into json to the foreground, but I need to do it manually, which doesn"t feel good.

is there any other better way

this is the bug of thymeleaf 2. Upgrading to thymeleaf 3 can resolve this bug;

thymeleaf2 is handled by json;
thymeleaf3. The jackson,jackson used by thymeleaf3 can solve the problem of mutual reference between the two classes by using @ JsonIgnoreProperties and @ JsonIgnore annotations.
