does kotlin arrow support Java 11?

[Jannis]

I think kotlin can do source compat up to java 15 iirc.

`JDK
Make sure to have the latest version of JDK 1.8 installed.

I use arrow on kotlin + jdk 14

[raulraja]

JDK 1.8 is only required to compile Arrow the library not to use it.

[Jannis]

I think the main problem is that we compile to jdk 1.8 compatible code and others compiling to 1.6 cannot use our inline functions because of that.
Tho 1.8 is kind of an important step from 1.6 in regards to how functions are treated on the jvm

[Jannis]

So using arrow requires at least source compat 1.8 or higher

This is misleading, not only do you need at least jdk 8, but also need to set the compiler target of your module to 8 or higher

I followed the subproject.gradle and it worked, thanks @Jannis

Please, improvements to the documentation are super welcome!! 👏

After this, we may be able to update this to at least 1.8 🤞

Thank you so much @pablisco!! 🙌
