Grails 5.x includes an older version of the legacy converters plugin than Grails 4.x

[spmcewen]

Expected Behavior

Grails 4.x includes legacyConvertersVersion 4.0.1 but 5.x and beyond include the older 4.0.0 release. 4.0.1 includes a fix for issue 11450 where rendering domain objects with composite keys throws a NPE.

I should be able to render a domain object that has composite keys as JSON with Grails 5

Actual Behaviour

With Grails 5 if you render a domain object with composite keys as JSON a null pointer exception is thrown
