If you do a database reverse engineering and create controllers for them and then restart the Roo shell it is unresponsive. Apparently it is trying to create some classes again:

This process starts fast, then becomes very slow so that the shell is blocked.

Apparently everything is fine if you do only the database reverse engineering i.e. no controller. Then the classes are also created again but that process is fast.

I attached a dumb of the MySQL database I am using and the Spring Roo log file.
