Is Java 8 support dropped because of JGraphT?

[juha.t...@gmail.com]

Choco 4.10.3 includes JGraphT 1.5.0.

"JGraphT requires JDK 11 or later to build starting with version 1.5.0." says JGraphT page.

I tried using choco-solver-4.10.3-jar-with-dependencies.jar. I got an error:

java.lang.UnsupportedClassVersionError: org/jgrapht/Graph has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0 (unable to load class [org.jgrapht.Graph])

Java 8 uses major version 52

Java 11 uses major version 55

So, is Java 8 support now ending? I am using a 32 bit JAVA runtime to run IBEX under windows. A fast check seems that the latest 32-bit runtimes are for Java 8. And there is no 64-bit IBEX for Windows, if I understand correctly.

dear Juha, 

I thought my release script was OK, but it appears to contain error, mixing Java 8 and Java 11.

I will try to fix it in that in the near future.

I based my work on this instructions:

https://maven.apache.org/plugins/maven-compiler-plugin/examples/module-info.html

I will double-check it does what I expected.

Can you confirm that you are using a Regular constraint?

Hi Charles!

Thank you for your efforts!

No, I am not using the regular constraint (regular, costRegular or multiCostRegular)

Best regards,

Juha
