我正面临在 Apache Chemistry OpenCmis 0.10.0 中执行 Session getObject 的 NullPointerException。我也在使用 Alfresco OpenCmis 扩展 0.6。
这是使用的代码：
OperationContext context = getSessionManager().getSession().createOperationContext();
context.setCacheEnabled(true);
context.setIncludeRelationships(IncludeRelationships.NONE);
CmisObject object = getSessionManager().getSession().getObject(uuid, context);
这是堆栈跟踪：

CMIS缓存中似乎出现了空指针，你见过这个错误吗？我在论坛中搜索过，但我没有看到这个错误。
谢谢！
