Defect

Dear Stefan Ferstl (@ferstl),

I have just tried to upgrade the Maven plugin for my current multi-module Maven project.

After performing the Maven plugin upgrade, the depgraph:reactor goal execution (mvn depgraph:reactor) fails with the following error message:

[ERROR] Failed to execute goal com.github.ferstl:depgraph-maven-plugin:4.0.0:reactor (default-cli) on project custom-maven-project: Execution default-cli of goal com.github.ferstl:depgraph-maven-plugin:4.0.0:reactor failed: Cannot invoke "String.equals(Object)" because the return value of "com.github.ferstl.depgraph.dependency.puml.PumlNodeInfo.getStereotype()" is null -> [Help 1]

Dear Stefan Ferstl (@ferstl),

I have just tried the 4.0.1 version. The depgraph:reactor goal has been executed successfully for my current multi-module Maven project.

Thank you very much for the prompt reply and the release!
