Spring java 11 getting spel issue EL1005E: Type cannot be found

Question

Getting below issue post upgrading Spring boot app to Java 11, this was working fine even on 2.1 spring boot on Jdk 8

Jdk : Correto 11

Spring boot : 2.2.13.RELEASE

Spring Integration : 5.2.11.RELEASE

Code :

 .route("headers.get(T(com.foo.integration.FlowHeaders).FEED).getProcessingMode()",
                  m -> m.subFlowMapping(Feed.ProcessingMode.stream, this.streamFlow(sinkStreamProcessingHandler))
                        .subFlowMapping(Feed.ProcessingMode.batch,
                              this.batchFlow(sinkBatchProcessingHandler, props))
                        .subFlowMapping(Feed.ProcessingMode.group,

Exception :

   ExceptionFlow - Exception in flow ... [EL1005E: Type cannot be found 'com.foo.integration.FlowHeaders']

UPDATE

This change somehow made it work though not completely sure as this is the same code as in the oob bean

@Primary       @Bean(IntegrationContextUtils.INTEGRATION_EVALUATION_CONTEXT_BEAN_NAME)
           public IntegrationEvaluationContextFactoryBean  evaluationContextFactoryBean(){
              var factoryBean = new IntegrationEvaluationContextFactoryBean();
              factoryBean.setTypeLocator(new CustomStandardTypeLocator());
              return factoryBean;
           }
        
           static class CustomStandardTypeLocator extends StandardTypeLocator {
        
              @Override
              public Class<?> findType(String typeName) throws EvaluationException {
                 LOG.info("Finding type {} in classloader {}", typeName, ClassUtils.getDefaultClassLoader().getName());
                 return super.findType(typeName);
              }
           }
