Spring 4 / Java Compatibility

The Spring 4 framework integrated with Smart GWT is no longer supported by Spring and is incompatible with Java 16+, so you need to either use an older version of Java (Java 8 or Java 11 (LTS)), or not use Spring.

If you absolutely need to use Java 16+, you can remove Spring from the Smart GWT server by removing all of the Spring JARs from your WEB-INF/lib server directory:

spring-beans-4.3.26.RELEASE.jar spring-core-4.3.26.RELEASE.jar spring-jdbc-4.3.26.RELEASE.jar spring-tx-4.3.26.RELEASE.jar spring-webmvc-4.3.26.RELEASE.jar spring-aop-4.3.26.RELEASE.jar spring-context-4.3.26.RELEASE.jar spring-expression-4.3.26.RELEASE.jar spring-orm-4.3.26.RELEASE.jar spring-web-4.3.26.RELEASE.jar isomorphic_spring.jar

and then removing the Spring configuration from your WEB-INF/web.xml:

  <!-- standard spring configuration -->
  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/applicationContext.xml</param-value>
  </context-param>    
  <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

Note that Spring 5, which is compatible with JDK 16+, can be used in your application. You just can't use Smart GWT's built-in Spring support, such as the "spring:" DMI target.
