The jar contains a rebel.xml which points to local windows user dir. Because of this, Jrebel warns on every server start:
JRebel: WARN Invalid ‘dir’ defined in class path of rebel.xml (jar:file:/C:/Users/Tobse/.m2/repository/com/vaadin/addon/locale/1.2.1/locale-1.2.1.jar!/rebel.xml):
Directory ‘C:/Users/nokdu/Desktop/LocaleComboBox/locale-addon/target/classes’ does not exist
Please release a version without that JRebel file.
