Well, _that's_ fun. I don't know if maybe Jython 2.5 behaves differently than 2.7 here, but `DatasetTestUtils.equals()` doesn't give you a useful result because _it's not being called_. Jython is invoking the base Object method, which is why you're getting referential equality behavior. I can't see any way to convince Jython to invoke the static equals method correctly. @pturmel may have some ideas?

I don't think it's a _bug_ (the behavior of the method itself is fine) outside of perhaps a bug in Jython, but fixing it is _not_ likely to be fun or low risk. I think your best options are to 1. script this yourself or 2. use Ignition Extensions: [Ignition Extensions - Convenience utilities for advanced users](https://forum.inductiveautomation.com/t/ignition-extensions-convenience-utilities-for-advanced-users/64615)
