Solving The Issue:

Add the latest AspectJ Tools dependency to the pom.xml.

                <dependency>
			<groupId>org.aspectj</groupId>
			<artifactId>aspectjtools</artifactId>
			<version>1.8.13</version>
		</dependency>

Please let me know if I have opened the ticket in a wrong place.

Still cant reproduce it. As @snicoll said it is probably an issue with your environment or else we would see many more people complaining about this.

A jar may also be corrupted on your machine, try running mvn dependency:purge-local-repository and try again
