Since you are using IBM J9, according to the Grails FAQ, the J9 need an argument to work well with Groovy, otherwise you may get a NoClassDefFound error:

Add -Xverify:none to JVM arguments

Somewhere, you try to use the class error: (and yes, Groovy thinks that the colon is part of the class name), either in the script you execute (i.e. there must be new error: somewhere) or you wrote something like groovysh error: or you import error: (maybe indirectly)
