Did i just find a bug in @canonical or am i thick ? #groovy

CanonicalIsWeirdScript

#!/usr/bin/env groovy

import groovy.transform.Canonical

def weird = new CanonicalIsWeird(a: 'first letter', b: 'second letter')
println "a: ${weird.a}"
println "b: ${weird.b}"

assert weird.a == 'first letter'
assert weird.b == 'second letter'

@Canonical
class CanonicalIsWeird {
    def a, b
}

I'm not sure, but it looks weird to me.

$ groovy -v
Groovy Version: 1.8.5 JVM: 1.6.0_29 Vendor: Apple Inc. OS: Mac OS X
$ ./test.groovy 
a: [a:first letter, b:second letter]

Indeed. I was expecting both assertions to pass.

Can you raise a Jira please. The workaround is to give types to your properties, e.g. String in this case - for at least the first property.
