Rick's right on both counts. TrackChanges doesn't eliminate proxies - it should just make them no-op.
We also need the proxies for for managed entities to track the state of non primitives (Dates, collections etc.). I don't think we have code in place that falls back and does a more thorough comparison if the proxies are not found though. Pinaki, The code changes are definitely untested - it's currently breaks the TestEnumToKernelConstantMappings test (which is rather banal, but probably there for a good reason). I'm not sure what you mean about not having a regression test environment. This problem would be found in a rather quick maven build. I understand not having multiple databases available, but running the regression bucket with derby should be doable. You can skip the long running locking tests with this arg: -Dsurefire.excludes.locking=**, if time is a concern. -mike On Wed, Jun 15, 2011 at 9:11 AM, Rick Curtis <[email protected]> wrote: > Javadoc from ProxyManagerImpl > > /** > * Whether proxies produced by this factory will use {@link > ChangeTracker}s > * to try to cut down on data store operations at the cost of some extra > * bookkeeping overhead.
