No support Jdk 8? #50

Closed yohanyflores closed 4 years ago

yohanyflores commented 4 years ago

I am trying to use version 3.0.0-RC1. But using jdk-8 I get this error:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/leadpony/justify/api/JsonValidationService has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0

@yohanyflores Thank you for reporting the issue. Java 8 should be still supported. I will examine why it happens.

@yohanyflores I tested the version 3.0.0-RC1 with Oracle JDK 8 and found it runs without error. Did you retrieve the artifact from the Maven Central?

@leadpony, Thanks for your quick response!

The artifact, I really hope, that you are getting it from "Maven Central".

However, when checking the version of my copy in .m2, with the following command:

javap -cp ~/.m2/repository/org/leadpony/justify/justify/3.0.0-RC1/justify-3.0.0-RC1.jar  -verbose org.leadpony.justify.api.JsonValidationService  | grep "major"

The output is:

major version: 53

So I downloaded the artifact that is in central maven and executing this command:

javap -cp ~/Downloads/justify-3.0.0-RC1.jar  -verbose org.leadpony.justify.api.JsonValidationService  | grep "major"

The output is:

  major version: 52

So, I don't think I'm getting the artifact from "Maven Central".

I must check that!

Thank you!
