Rant: Why I hate Java Client

So I get this backtrace (see below).

So this is some sort of config problem, brought on somehow by the fact that I've moved all the .jar cruft we had hanging out in /Library/Java/ Extensions into a framework. It looks like the server is forwarding some sort of EOGeneralAdaptorException to the client which might have had useful information in it but client has no idea how to unarchive it because for some reason it can't access eocasses, so it then throws a completely different exception on the client side.

Debugging all this is like being put into a straightjacket, handcuffed, gagged, thrown into a pit, and then asked to make a full course dinner.

Plus none of this stuff works for me from Eclipse, because no one ever got around to porting it fully to Eclipse when they moved the rest of the projects over.

Meanwhile, the Support folks are whining, because I lowered the boom and told them Java Client was going away, so they have to adjust to an app that isn't just a thin coat of paint over Direct2JavaClient and actually come up with a specification for what all they use this piece of shit for.

I've spent 40 hours over the last 2 weeks fighting with this stupid thing. It takes me about an hour to build a screen in the new app that will replace this crap.
