[rdf4j-dev] Java Module System?

[Niclas Hedhman <niclas@xxxxxxxxxxx>]

Hi,
I am in the process of upgrading from Java 8 to Java 17, and I am 
running into problems with RDF4J in conjunction with the Java Module 
System (a.k.a jigsaw)

Since version 5 is about to come out and the MANIFEST.MF states 
"Build-Jdk-Spec: 11", wouldn't it be a good time to become compatible 
with Java Module System?

It is fairly difficult to work around the issues with RDF4J's many jar 
files, since jar some jars contain the same packages, which Java Module 
System is unhappy about.

E.g. rdf4j-queryparser-api-5.0.0-M2.jar contains 
org.eclipse.rdf4j.query.impl, which is also present in 
rdf4j-query-5.0.0-M2.jar, but there are many more (removing 
rdf4j-sail-base, resolved 100s of compile errors).

Cheers
Niclas
