Spring Framework 5 is a major Spring release with a substantial increase in the baselines. Along with the increase in baseline versions for Java, Java EE, and a few other frameworks, Spring Framework 5 removed support for a few frameworks:

• Portlet
• Velocity
• JasperReports
• XMLBeans
• JDO
• Guava

If you are using any of the preceding frameworks, it is recommended that you plan a migration and stay with Spring Framework 4.3, which has support until 2019.
