I am asked to run a spring boot application inside a java web application that doesn’t use a dependency management tool so i am running my spring-boot-app without an embedded tomcat the issue was when i tried to use hibernate 5 it seems that the project is dependant on hibernate 3 such as org/hibernate/jdbc/JDBCContext
I need a way to use both hibernate versions since it is not possible to refactor the old code due to security issues in the company

I am using spring-boot-1.5.22RELEASE
with spring 4.3.25.RELEASE
my spring boot app is running fine but the other source folders are having this issue
