When I see two instances of the same

object

in my application, what might be the issue? Seems to be possible

Just guessing, but could it be from the different process?

That was also my guess, but it really seems to be the same

it's a spring boot application fwiw

multi module

Could be Spring creating “beans” by using reflection to invoke private constructors. JUnit 5 has the same bug.

yeah something like that. I can see it's being initialized during startup and once again later

Different classloaders maybe?

@sdeleuze any known issues with

object

?

oh I think I have an idea thanks @hho

you're definitely right, it's being loaded twice with two different classloaders

maybe it's not a known issue because this particular object is being used during the spring init already, which might not be the common scenario

Classloading issues can happen when Devtools is enabled

Found that out the hard way

Removed them already, not the issue

No you're actually right 🤦‍♂️ I removed them only partially

I have not played that much with

object

yet, I mostly used it with Exposed.
