java.lang.IllegalAccessError while starting Spring application on Tomcat 8

Question

I am getting this very strange error when i try to run the project on Tomcat 8:

INFO o.s.web.context.ContextLoader - Root WebApplicationContext: initialization started . INFO o.s.w.c.s.AnnotationConfigWebApplicationContext - Refreshing Root WebApplicationContext: startup date [Mon Jun 29 10:59:34 CEST 2015]; root of context hierarchy . INFO o.s.w.c.s.AnnotationConfigWebApplicationContext - Registering annotated classes: [class com...]

ERROR o.s.web.context.ContextLoader - Context initialization failed java.lang.IllegalAccessError: tried to access method org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingletonMutex()Ljava/lang/Object; from class org.springframework.context.event.AbstractApplicationEventMulticaster

My first thought was that there are some errors in Spring version but i cannot find anything. This is pretty much same project setup i have used couple of times, with the only difference that this is java 8 project.

Project is Dynamic Web Module 3.1.

Bellow are dependencies from the .pom file, i don't see any collisions in the versions.

Kindly help if somebody encountered this before.

Answer 1

The problem is you are mixing different versions of Spring which are incompatible. Regardless you should never mix jars from different versions of any framework (Spring, Hibernate, JSF etc.) as that is trouble bound to happen.

The best way is to simply use the Spring IO Platform.

Add the following to your pom

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>1.1.2.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

Then remove the versions in your pom as the versions are now being managed by the platform-bom, you should now have versions that work together and no more conflicting versions. For a list of managed version check this appendix.
