Observed behaviour

Outdated dependency: SpringFramework

Expected behaviour

upgrade springframework 4.3.23 instead of 4.3.22 (Release date: 2019.04.01)

• https://spring.io/blog/2019/04/01/spring-framework-5-1-6-5-0-13-and-4-3-23-available-now
• https://spring.io/projects/spring-framework
  • https://github.com/spring-projects/spring-framework/releases/tag/v4.3.23.RELEASE
  • https://github.com/spring-projects/spring-framework/milestone/212?closed=1

The 4.3.x line reaches an extended support phase now, with no regular maintenance being planned beyond 4.3.22 anymore but serious issues still to be addressed in infrequent releases on demand. No official EOL date has been set yet; we expect it around mid 2020.
