升级后大量的NPE异常 #120

Closed GoogleCodeExporter closed 9 years ago

结合hibernate使用，大量的抛出这样的一场。

这个堆栈不完整吧？

貌似没看到xmemcached的类名。你说的升级是指什么？升级xmemcac
hed还是hibernate-memcached?请详细描述下。
如果是升级xmemcached，是从哪个版本升级到哪个版本。

从这个异常来看，是hibernate-memcached抛出的，你是升级hibernate-
memcached吧？

升级了xmemcached

您真是惜墨如金的。请描述下是从xmc哪个版本升级到哪个版��
�吧。从你给出的堆栈来看，似乎跟xmc没有多大关系。
