Multiline Messages in Message Bundles

I would like to make 开发者_Go百科use of the message bundles feature in grails, but always run into the problem that I need multiline messages for text (instructions or help text for example).

Is there a way to create multiline messages or do I have to create single line messages with <br />s or \ns in between?

Or is it the wrong approach for longer text?

I believe you can simply end the line with a trailing slash (\) and continue on the next line in Java Properties files.
