With Solr 8’s support ending in June 2024, it’s crucial for local environments to transition to Solr 9. Unlike cloud installations of SAP Commerce (where you can easily switch Solr versions via manifest.json), local setups encounter difficulties in switching between Solr versions.
In Java 11 was removed support of JAX-WS (JSR 224), and related classes like ant WsImport task, which are highly used in hybris installations for third-party SOAP integrations. For example, cybersource integration extension rely on both wsimport (generates cybersource client from wsdl during ant build) and JAX-WS to execute SOAP requests.
Starting from January 15, 2020 maven central repository is not supporting access via http://repo1.maven.org/maven2 due to security reasons. Unfortunately under the hood hybris uses ant-maven-task, which is not maintained since 2011 and has hardcoded link to http version of maven central.
