Spring Data Neo4j: Using the server with an embedded

Question

I'm trying to configure my application context in order to be able to use the Neo4j server with an embedded graph in my app without much success. I'm using Spring Data at the same time (both Mongo and Neo4j repositories approach). This is my application-context, which isn't running:

<context:component-scan base-package="org.domain.team.project.*"/>

<mongo:repositories base-package="org.domain.team.project.data.repositories.mongodb"/>

    <!-- Neo4j -->
    <!--  <neo4j:config storeDirectory="/data/production/graph.db"/> -->
    <neo4j:repositories base-package="org.domain.team.project.data.repositories.neo4j"/>

    <neo4j:config graphDatabaseService="graphDatabaseService" />
    <bean id="graphDatabaseService" class="org.neo4j.kernel.EmbeddedGraphDatabase"
    destroy-method="shutdown">
        <constructor-arg index="0" value="/data/production/graph.db" />
        <constructor-arg index="1">
            <map><entry key="enable_remote_shell" value="true"/></map>
        </constructor-arg>
    </bean>
    <bean id="serverWrapper" class="org.neo4j.server.WrappingNeoServerBootstrapper" 
        init-method="start" destroy-method="stop">
            <constructor-arg ref="graphDatabaseService"/>
    </bean>

If I don't use this approach and specify simply the store directory (commented line) everything runs fine. I suspect it's a version between SDN and neo4j-server issue. This is my POM:

  <properties>
    <spring.data.mongo.version>1.1.0.RELEASE</spring.data.mongo.version>
    <spring.data.neo4j.version>2.1.0.RELEASE</spring.data.neo4j.version>
  </properties>

  <dependencies>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-mongodb</artifactId>
        <version>${spring.data.mongo.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-neo4j</artifactId>
        <version>${spring.data.neo4j.version}</version>
    </dependency>
    <dependency>
        <groupId>org.neo4j.app</groupId>
        <artifactId>neo4j-server</artifactId>
        <version>1.8.2</version>
    </dependency>
    <dependency>
        <groupId>org.neo4j.app</groupId>
        <artifactId>neo4j-server</artifactId>
        <classifier>static-web</classifier>
        <version>1.8.2</version>
    </dependency>
  </dependencies>

Its parent has as a dependency Spring(core,context,test) 3.2.0 Release.

The concrete error being displayed is:

Caused by: java.lang.NoSuchFieldError: query_cache_size
    at org.neo4j.cypher.ExecutionEngine.org$neo4j$cypher$ExecutionEngine$$getQueryCacheSize(ExecutionEngine.scala:95)

    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1483)
    ... 47 more

which as far as I am concerned, should be no problem as the default value is 100. The SDN doc does not talk too much about it. Any suggestions?

Thank you all in advance.

Looks like version compatibility issue. For me below combination is working fine

spring-data-neo4j : 2.1.0.RC4
spring-data-mongodb : 1.1.0.RELEASE 
neo4j-server : 1.8
static-web : 1.8

Further, I am using-

Spring framework version : 3.1.2.RELEASE
Neo4j version : 1.8
mongodb version : 2.2.2
mongo-java-driver : 2.9.1
slf4j : 1.7.2
