AW: Wrong fallback language

Problem solved!
Spring fallback is by default the system language - in my case German.
I modified the bean "messageSource" at "system/conf/global-system.xml" :
	<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource"
		p:cacheSeconds="%{idp.message.cacheSeconds:300}"
		p:basenames-ref="#{'%{idp.message.resources:shibboleth.MessageSourceResources}'.trim()}"
		p:fallbackToSystemLocale="%{idp.message.fallbackToSystemLocale:false}"
		p:defaultEncoding="UTF-8" />

At "idp.properties" I added the property "idp.message.fallbackToSystemLocale".
