ReflectionUtils.makeAccessible() in different .jar files lead to java.lang.NoSuchMethodError Exception on openJDK - spring

Question

i have the following problem: we raised our application from java6 with tomcat6 to java8 with tomcat8. Starting the application on our local machines with Oracle Java 8 worked witouth problem. But on our server we get
java.lang.NoSuchMethodError: org.springframework.util.ReflectionUtils.makeAccessible(Ljava/lang/reflect/Constructor;)V

We investigated the problem and the ReflectionUtils.makeAccessible() Method is provided by spring-core-2.0.8.jar and org.springframework.core-3.0.4.RELEASE.jar
Our server is running OpenJDK 8 instead of Oracle Java 8 and it seems like the application tries to use makeAccessible() from the spring-core-2.0.8.jar instead of the org.springframework.core-3.0.4.RELEASE.jar. When we delete the spring-core-2.0.8.jar in our lib Folder the application starts without a problem. Unfortunately the spring-core-2.0.8.jar comes as a maven transitive dependency from a maven hibernate dependency, therefore we need this jar.
Do you have any ideas how to solve this?
Thanks in advance, best regards
