Fix

Exclude the transitive dependency and add newer version: 

		<dependency>
			<groupId>de.dailab.model.domain</groupId>
			<artifactId>CommonDomainModel</artifactId>
			<version>${domain.model.version}</version>
			<exclusions>
				<exclusion>  <!-- declare the exclusion here -->
					<groupId>log4j</groupId>
					<artifactId>log4j</artifactId>
				</exclusion>
			</exclusions>
		</dependency>
		<dependency>
			<groupId>log4j</groupId>
			<artifactId>log4j</artifactId>
			<version>1.2.17</version>
		</dependency>
