My bad, a misconfiguration caused that
I'm curious to know how you misconfigured that? Is there something else we could have done to make the install go better?
Installing Jopr out of box should never have done this - I can't say we've ever seen this happening to someone taking the GA and installing it.
Well I just unzipped the whole thing with WinRAR and forgot about error messages I got at this time, saying that some files (I later realized it was those missing inner classes) could not be found since their path+name were longer than 260 chars.
Unzipping on a Linux platform did work well though.
Ah... yes... the "Windows paths too long" problem.
This is documented - we recommend that people read through the installation documentation before installing the server. There are little nuggets of information like this in there.
Specifically the big red box titled "Windows Installation" that warns you about too-long pathnames.
