yes and I can take a closer it.

Indy is ready to use very early during VM initialization before initPhase2 where the module system is initialized.   AFAIU, indy is needed for the object methods for records i.e. `equals`, `hashCode`, and `toString`.  Just record object instantiation and accessing its final fields don't use indy.
