[New Maven Module wizard] : Dashes '-' disappeared in Module name when I define a name for my artifactId.

 I am used to include dashes (' -') in my artifactId (and groupId) names when I create a new maven module via the IntelliJ wizard (File -> New Module). Example: my-maven-artifact

I noticed that as of 2016.3.4 these dashes automatically(by default) disappear: mymavenartifact.

I prefer using dashes.

Why has this changed? Or is this a bug?
