nashorn-dev Digest, Vol 82, Issue 1

Thu Apr 16 13:38:21 UTC 2020

Hi,

FWIW I can only reiterate concerns, probably already expressed by many people.

This is to my knowledge the first time that Java breaks backwards compatibility.
It creates a precedent and the impact of that is impossible to anticipate…

Add to that that the Detroit project has been dropped in favor of GraalVM which imho is a terrible mistake…
The GraalVM approach is great for DSLs, but for mainstream languages you want to stick to constantly evolving implementations.

I obviously don’t expect that this email is gonna stop the below from happening .
But if this turns out to be a bad decision, these comments will be in writing.
