StringPrimitive not serializable breaking EHRbase HA deployments

[subigre]

Before reporting an issue

• I have searched existing issues
• I have reproduced the issue with the latest release

Environment information

{
  "ehrbase_version": "2.24.0",
  "openehr_sdk_version": "2.27.0",
  "archie_version": "3.13.0",
  "jvm_version": "Eclipse Adoptium 21.0.8+9-LTS",
  "os_version": "Linux amd64 6.8.0-53-generic",
  "postgres_version": "PostgreSQL 17.6 on x86_64-pc-linux-gnu, compiled by gcc (Debian 12.2.0-14+deb12u1) 12.2.0, 64-bit"
}

Steps to reproduce

1. Deploy the latest EHRbase version using Redis for caching.

   # ...
   spring:
     cache:
       type: redis
     data:
       redis:
         host: redis
         port: 6379

2. Upload a template using: POST http://localhost:8080/ehrbase/rest/openehr/v1/definition/template/adl1.4

Alternative:

1. Run the following main class

package org.ehrbase.test;

import org.ehrbase.openehr.sdk.webtemplate.model.WebTemplate;
import org.ehrbase.openehr.sdk.webtemplate.parser.OPTParser;
import org.openehr.schemas.v1.OPERATIONALTEMPLATE;
import org.openehr.schemas.v1.TemplateDocument;
import org.springframework.core.io.ClassPathResource;

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;

public class WebTemplateSerialization {

    public static void main(String[] args) {
        ClassPathResource resource = new ClassPathResource("KDS_Diagnose.opt");

        TemplateDocument document;
        try {
            document = TemplateDocument.Factory.parse(resource.getInputStream());
        } catch (Exception ex) {
            throw new IllegalArgumentException("Failed to parse template", ex);
        }

        OPERATIONALTEMPLATE operationalTemplate = document.getTemplate();

        WebTemplate webTemplate = new OPTParser(operationalTemplate).parse();

        try (ObjectOutputStream os = new ObjectOutputStream(new FileOutputStream("template.dat"))) {
            os.writeObject(webTemplate);
        } catch (IOException ex) {
            throw new IllegalStateException("Failed to serialize web template", ex);
        }
    }
}

Expected behavior

Template should be uploaded and added into the cache.

Actual result

ehrbase-ehrbase-8c6dcdb9-hxlfj-ehrbase.log
