> jdk.net.ExtendedSocketOptions causes compatibility problems with newer JDKs
> when using Java 8 as a release target (--release compile option).
> Newer JDKs fail to import jdk.net package when targeting Java 8 apparently
> due this feature being considered invalid for Java 8

> I had to disable release target validation due to this problem when upgrading
> our maven POM. Please note the check was not used prior to the upgrade.
> Given that the animal sniffer plugin has been discontinued in favor of JDK
> release target validation, we have lost a valuable quality control mechanism
> and a safe-guard.
> The best course of action would be just upgrade to Java 17 and forget about
> Java 8 compatibility woes.
> Alternatively, we could consider removing direct import of jdk.net classes
> and go back to using reflection.
