Error with Sonar analysis

I am getting an issue when anaylzing my project with the sonar maven plugin.

[ERROR] [15:48:04.269] Unable to create symbol table for : /path/projetc/src/main/java/my/package/Person.java

• Javaslang version: 2.0.6
• sonar-maven-plugin version: 2.6
• SonarQube version: 5.6.2

It seems that the ?.class is the origin of the issue.

That's the class with an unicode λ as it's name. It got renamed to Lambda. Switch to the renamed project io.vavr:vavr, it has it's first release as 0.9.0 in the central maven repository.
