In version 3.0.2 the file META-INF/INDEX.LIST in the jar has the entry tooltips4vaadin.jar instead of tooltip-<version>.jar like older version have.
When debugging a spring boot application, there come up some exceptions together with the JarIndex.
It tries to find e.g.
file:/C:/Users/soenke.reimer/.m2/repository/dev/mett/vaadin/tooltip/3.0.2/tooltips4vaadin.jar
which does not exist.
The application itself works correct.
