The static intializer block in the GrailsUtil class has some Engrish in the log messages that are output if the Grails version cannot be read from the MANIFEST.MF. (Well it reads like Engrish to me.)
'... Are you sure it the grails-core jar ...'
I think this wants to be something like:
'... Are you sure the grails-core jar ...' (But maybe you don't want to hardcode the name of the .jar file in there :|)
