Subject: Re: Feedback on JEP draft: Lazy Constants (Second Preview)

Spring Data has a Lazy [0] type that is a nice fit conceptually and when used as field type without reserving too much name complexity. Therefore, +1 for renaming to Lazy.

Also, appreciate the successor JEP. Using StableValue with a Supplier (to back Spring Data’s Lazy with stable values) had some rough edges, the new approach is much more polished.

Cheers,
Mark
