Bug 950962 – app-misc/elasticsearch-8.17.3 fails to start: java.lang.module.FindException: Module jdk.attach not found, required by org.elasticsearch.entitlement

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description nebojsa 2025-03-08 23:39:17 UTC]

elasticsearch-8.17 introduced dependency on jdk. Without a jdk installed, it fails to start complaining about jdk.attach module not found.
After installing virtual/jdk:17, it works without a problem

Reproducible: Always

Usually if using virtual/jdk, it should go in DEPEND according to https://wiki.gentoo.org/wiki/Java_Developer_Guide#JDK.2FJRE.
In RDEPEND you put virtual/jre - and don't forget to inherit either of 
java-pkg-2.eclass of java-pkg-opt-2.eclass.

This package is not compiled - it is a binary bundle, that's why it does not inherit java-pkg-*.eclass.
Further, it depends on jdk runtime, and not on jre runtime. Running it with jre runtime is what produces the error.
If anything, package name could be changed to better reflect its contents, to elasticsearch-bin, and a warning could be issued to the user about either setting up jdk as system-vm or setting ES_JAVA_HOME in /etc/conf.d/elasticsearch to point to one.

afaik, binary blob should never depend on jdk. if it does, there's something wrong.
