服务器重启有几率触发这个问题(Server restart has a chance to trigger this problem)

maybe a multithreading related issue during initial build up of metadata (FSTClassInfo).

• try 2.50, I made some fixes in this area (actually an undisclosed company made a reproducable testcase of 2000+ generated classes to reproduce this), has been fixed
• if this does not help please try to create a testcase reproducing this

[RuedigerMoeller]

seems fixed with 2.5x as no further response
