how can stop this?

1. print out dependency tree executing following command:

   mvn dependency:tree 

2. locate offending library fetching 4.0.6.release version of spring-jms.

3. let's offending library some-library responsible fetching 4.0.6.release version of spring-jms library. make following changes child pom.xml exclude spring-jms library.

   <dependency>    <groupid>some.group</groupid>    <artifactid>some-library</artifactid>    <exclusions>         <exclusion>             <groupid>org.springframework</groupid>             <artifactid>spring-jms</artifactid>         </exclusion>     <exclusions> </dependency> 

4. add new 4.1.0.release release of spring-jms in child pom.xml add new version.

   <dependency>     <groupid>org.springframework</groupid>     <artifactid>spring-jms</artifactid>     <version>4.1.0.release</version> </dependency>
