In the parent pom we have spring repository defined that we need for com.springsource.commonj artifact in javaee/jobexecutor-ra - CommonJ container managed threading:
https://github.com/camunda/camunda-bpm-platform/blob/6a7c5a90d39c861776cbef89def47321b965e30e/parent/pom.xml#L629-L633

The url's repository is no longer available and the correct one is:

• https://repo.spring.io/plugins-release

Why we didn't face an issue because of this?

• The artifact is cached already in our internal nexus.
• Nobody reported it so far (either the people don't build the javaee subproject or they have the correct repository already configured).
