[jira] [Commented] (CALCITE-7307) A new added dependency conflicts with Java 9+ and JPMS

    [ https://issues.apache.org/jira/browse/CALCITE-7307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18041141#comment-18041141 ] 

Issac Garcia commented on CALCITE-7307:
---------------------------------------

A workaround I found in my project is to exclude the transitive dependency joou-java-6 & add as dependency the one proposed  [https://github.com/jOOQ/jOOU] for java 9+
It seems to work, packages are the same, and code seems the same, with a small difference on the `hash` method, but is a hacky solution which can break in the future if code diverges

>             Project: Calcite
>          Issue Type: Bug
>    Affects Versions: 1.41.0
>            Reporter: Issac Garcia
>            Priority: Minor
>
> In Calcite-core during the work of this issue https://issues.apache.org/jira/browse/CALCITE-1466 a new introduced dependency seems problematic to work with new Java versions.
> I receive the following error with Java 21 in a project with JPMS:
>  
> {code:java}
> Unable to derive module descriptor for joou-java-6-0.9.4.jar ... Caused by: java.lang.IllegalArgumentException: joou.java.6: Invalid module name: '6' is not a Java identifier {code}
> It seems JPMS does not like the "6" in the artifact name.
