ehcache disk write error of Gradebook2 (GradeStatistics)

Description

Similar to GRBK-1363, we are seeing ehcache errors with Sakai 2.9 and GB2 as follows:

2013-04-03 09:54:08,627 [org.sakaiproject.gradebook.gwt.sakai.gradebookservice.cache.data] ERROR net.sf.ehcache.store.disk.DiskStorageFactory - Disk Write of gb2_calculateStatistics_328959_328_328.0 failed:
java.io.NotSerializableException: org.sakaiproject.gradebook.gwt.sakai.model.GradeStatistics

I believe the impact is benign except for filling up the logs, but don't know for sure.
