I am trying to upgrade to Hibernate 5.4.13 but my server fails to start with below error.

[log4j2] 21:13:07,426 WARN [ClassPathXmlApplicationContext] Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘tomcat.server.context’ defined in URL [jar:file:/data/sfsf/workspace/trunk/tomcat-sfs/sf\_lib/idl-sftomcat-service-trunk.8.5.43-sf.202003130051.jar!/beanRefContext.xml]: Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.context.support.ClassPathXmlApplicationContext]: Constructor threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘sessionFactory’ defined in class path resource [platform/transaction/tomcat-transaction-context.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/property/BasicPropertyAccessor

I know the BasicPropertyAccessor is no longer supported.But this call is made from other library and not from my code. Do I need to upgrade other libraries ? If yes which is ? OR how can I solve this problem? There is no help available on this forum regarding above issue.
