Spring JPA and log4j version conflict

Question

I'm trying to set up a Spring JPA Hibernate simple project with Atmosphere framework.

This is Maven dependency

    <!-- Spring framework -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.1.5.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>4.1.5.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.3.8.Final</version>
    </dependency> 
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>4.3.8.Final</version>
    </dependency>
    <dependency>
        <groupId>org.atmosphere</groupId>
        <artifactId>atmosphere-runtime</artifactId>
        <version>2.1.4</version>
    </dependency>
    <dependency>
        <groupId>net.wimpi</groupId>
        <artifactId>telnetd-x</artifactId>
        <version>2.1.1</version>
    </dependency> 
   <!-- Logging with SLF4J & LogBack -->
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.5</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.0.13</version>
        <scope>runtime</scope>
    </dependency>

But i am getting version conflict with log4j and Spring hibernate JPA.

Please help, thanks

Try removing the log4j transitional dependency from telnetd-x:

<dependency>
    <groupId>net.wimpi</groupId>
    <artifactId>telnetd-x</artifactId>
    <version>2.1.1</version>
    <exclusions>
        <exclusion>
            <artifactId>log4j</artifactId>
            <groupId>log4j</groupId>
        </exclusion>
    </exclusions>
</dependency>

This lib is using an old version of Log4j (1.2.9) and it can be the source of your issues.
