I'm looking at a kotlin sdtlib dependency in our java projects (pulled in by okhttp3) at version 1.4.10; I suppose I can upgrade to 1.9.0. is there a good overview over which version runs on which JVM version?

[CLOVIS]

The stdlib supports Java 1.6 until version 1.4, and requires Java 1.8 since Kotlin 1.5

[Bernhard]

so no brainer for java 11 I guess

[CLOVIS]

yes

[Bernhard]

thank you clovis

[CLOVIS]

Most libraries in the ecosystem support Java 11

[CLOVIS]

Still, for server-side development you should do what you can to use the latest Java version, even if it's only for the performance improvements

[Bernhard]

we do, it's a question of if the customer is willing to pay money to upgrade their stack which he doesn't right now

[James Richardson]

Tbh, it's the other way round in my mind.. people should pay to stick on old versions. Much more expensive to support old jvm, libs, anything...

[loke]

While you're not wrong, it's often hard to impose such requirements after the fact. And you can't really impose such requirements if you're a startup looking to sign your first customers.

[loke]

So many companies end up with legacy contracts that allows the customer to stay on old versions for a long time.

the issue is more the proprietary framework on top; SAP hybris (built on Spring); license changed so you need to move to their cloud offering, last upgrade to a new version before that took 1.5 months of work; so it's not just a simple JVM upgrade
