GPMONGODB-134: Javassist NoClassDefFoundError when saving a mocked domain

[graemerocher]

Original Reporter: hardwickj
Environment: OS X 10.7, Grails 1.3.7
Version: 1.0.0.RC1
Migrated From: http://jira.grails.org/browse/GPMONGODB-134

so, say we have....

@mixin(DatastoreUnitTestMixin)
class SimpleTests extends GrailsUnitTestCase {

void testCorrelatePlace() {
    mockDomain(Embeddee)
    mockDomain(Embedder)
    def embeddee = new Embeddee(name: 'ABC123)
    def embedder = new Embedder(name: 'XYZ789', embeddee: embeddee).save()  // <- BOOM!
}

}

Ala the above code snippet, when attempting to save a domain class that contains another domain class, both of which have been mocked using the mixin mockDomain functionality, I receive the following NoClassDefFoundError:

etc...

Manually adding a BuildConfig dependency for javassist:

compile 'javassist:javassist:3.12.1.GA'

...solves this.

1 of the 2 tests in this example project demonstrates this. It appears to also happen by including the mocked instances when calling mockDomain ala the failing test.
