NoClassDefFoundError: DataAccessException using spring

Question

I know this has been discussed a lot, but somehow none of the previously asked questions is applicable to my case. When loading my application I get the following stacktrace:

In most of the threads I read concerning similar errors people were indeed missing the spring-tx jar which I definately don´t. It is declared in my maven dependencies along with the other spring jars neededd like this:

        <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-tx</artifactId>
        <version>4.2.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-beans</artifactId>
        <version>4.2.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>
        <version>4.2.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.2.0.RELEASE</version>
    </dependency>

When investigating my deployed output the jars are there as well. Nevertheless the mentioned error is thrown. I am really desperate with this. Please note, that the application is not a WebApp but kind of a standalone application loaded from another program.

Funny thing is that my colleague can´t reproduce the error. For that reason I guess it´s some kind of race condition between my JavaFX loader loading the result of the spring-jdbc query into its datamodel. I don´t have any proof for this, it´s just kind of a gut instinct. Any help or tipp would be really appreciated. If further information is needed please let me know.

Class : org.springframework.dao.DataAccessException is defined in Spring-DAO. Check if have below dependency.

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-dao</artifactId>

</dependency>
