It seems that the wizard looks for 3 (switchyard-api, kie-api and fuse-integration-bom) dependencies before the wizard is displayed. If a user has many repositories defined in settings.xml then it will take too long to display the wizard. Moreover, during that time the IDE doesn't respond and it seems that it has freezed.
The only information is only in the command line (see the attached log file).

Note that this happens only for the first time.
