操作无效：已关闭 Lob。 ERRORCODE=-4470, SQLSTATE=null

DB2 9.7 + JBMP4.4 报了这个异常。
从异常信息中得到的信息是，是由DB2发生的异常：
com.ibm.db2.jcc.am.SqlException: [jcc][10120][11936][3.57.82] 操作无效：已关闭 Lob。 ERRORCODE=-4470, SQLSTATE=null
导致JBPM内部发生了异常：
couldn't extract bytes out of blob

org.jbpm.api.JbpmException: couldn't extract bytes out of blob


根据网上的信息已经尝试过如下操作：
1.在执行db2set DB2_RESTRICT_DDF=true，重新数据库
2.在数据库连接url中加入参数：progressiveStreaming=2;
3.在数据库连接url中加入参数：driverType=4;fullyMaterializeLobData=true;fullyMaterializeInputStreams=true;progressiveStreaming=2;progresssiveLocators=2;
4.在数据库连接url中加入参数：lob threshold=11777216;
5.在Hibernate的配置中将auto此属性去掉

都无效，想看看有人遇到到同样的情况吗？
