StackOverflowError during saving in gorm 6.10

[demon101]

One time in tests I got StackOverflowError during saving or entity with beforeUpdate logic.
It happens only once during test, I'm not sure I can reproduce. But I will provide project with same domain graph. As I can see, on every step it saves Contract entity with same ID
Same code works well in prod with GORM 6.0.12

Example Application

https://github.com/demon101/grails-bug-cyclic-save

[graemerocher]

The referenced example application includes no code

[demon101]

@graemerocher have pushed one minute ago. I was on the progress.
I have tried to make same with my app domain structure. But I didn't reproduce the bug in the app. I hope, it will be enough

[graemerocher]

Saving objects in events is not supported, as the events are triggered in the middle of a flush. This is mentioned in http://gorm.grails.org/latest/hibernate/manual/index.html#advancedGORMFeatures

[demon101]

damn, right, I've come across this.

but it is really misleading that the functionality stops working a little at each update

Sorry. I think the issue can be closed
