Describe the issue
I am trying to find a minimal JDK to execute Enso programming language and environment on, I am using jlink. I am trying to get things down as much as I can, but Graal.js seems to need java.desktop! (via a transitive dependency thru regex):
java.lang.module.FindException: Module java.desktop not found, required by org.graalvm.shadowed.icu4j
$ rm ./built-distribution/enso-engine-0.0.0-dev-linux-amd64/enso-0.0.0-dev/component/icu4j-24.0.0.jar
java.lang.module.FindException: Module org.graalvm.shadowed.icu4j not found, required by com.oracle.truffle.regex
$ rm ./built-distribution/enso-engine-0.0.0-dev-linux-amd64/enso-0.0.0-dev/component/regex-24.0.0.jar
java.lang.module.FindException: Module com.oracle.truffle.regex not found, required by org.graalvm.js
E.g. org.graalvm.js needs com.oracle.truffle.regex and that one needs org.graalvm.shadowed.icu4j and that one needs java.desktop.
I assume the java.desktop dependency isn't necessary - maybe it can be made optional... can such a change be made in your build?
Steps to reproduce the issue
I am generating the minimal JDK as:
$ /graalvm/bin/jlink --output jdk --add-modules java.net.http,jdk.unsupported,java.sql,jdk.management,jdk.jfr
$ ./jdk/bin/java --list-modules
java.base@21.0.2
java.logging@21.0.2
java.management@21.0.2
java.net.http@21.0.2
java.sql@21.0.2
java.transaction.xa@21.0.2
java.xml@21.0.2
jdk.internal.vm.ci@21.0.2
jdk.jfr@21.0.2
jdk.management@21.0.2
jdk.unsupported@21.0.2and then I'd like to invoke Graal.js and its components on the generated JVM. It fails with java.lang.module.FindException as shown above.
Expected behavior
java.desktop is a huge module and it shouldn't be needed for running Graal.js - having that fixed would allow using Graal.js & co. in headless JDKs without java.desktop & co. modules.
