I think all those checks need to remain for soft upgrade mode, otherwise
your changes allow referential actions to be created that will not be
handled correctly by 10.0 engines.
The runtime code could probably remain as-is, in soft upgrade mode it
would just handle cases that wouldn't exist. So only the DDL code would
need checkVersion() calls.
Dan.
I have modified my patch to incorporate Dan's request. The new patch
looks at the database version and applies the V10.0 checks during
referential constraint DDL if the database is V10.0 (soft upgrade). The
new patch is attached to Derby-338
(http://issues.apache.org/jira/browse/DERBY-338).
