See this ticket for more information https://jira.grails.org/browse/GRAILS-10183

[jmiranda]

Either of these workarounds solves the problem:

grails -noreloading run-app

OR

BuildConfig.groovy: grails.project.fork = false

[jmiranda]

Actually, the second solution doesn't work for Grails 2.2.1 because forked execution wasn't introduced until Grails 2.3.x.
