Bug fix in ScopeAdapter: the value was lost if the MetadataScope was not an instance of DefaultMetadataScope.
This bug has been identified by the port to trunk (it has not been identified by the tests on the JDK8 branch,
but the fact that the tests on trunk sometime follow a different code path has made this bug visible).
