Drop JDK8 support #3522

Closed pomadchin closed 4 months ago

pomadchin commented 1 year ago

GeoTools is already JDK11+; JDK11 is well supported by Spark and other libs from the Hadoop ecosystem; JDK11 is on EMR as well.

I'm thinking of dropping JDK8 once GeoTools 30 is released.

Latest CI MacOS image does not support jdk8

I guess there are no longer needs in supporting JDK8 any more.
