activiti 添加bpmn文件报错

activiti 添加bpmn文件时报错：请教下各位
(关键是：有的bpmn文件可以正常添加，有的文件就会报如下错误：)
我的代码：
InputStream inputStreamBpmn = this.getClass().getResourceAsStream("exclusiveGateway.bpmn");
Deployment deployment = processEngine.getRepositoryService()
.createDeployment()
.addInputStream("exclusiveGateway.bpmn", inputStreamBpmn)
.deploy();

                下面是报错信息:

org.apache.ibatis.exceptions.PersistenceException: 

Error updating database. Cause: java.sql.SQLException: ORA-01460: 转换请求无法实施或不合理

The error may involve org.activiti.engine.impl.persistence.entity.ResourceEntity.insertResource-Inline

The error occurred while setting parameters

SQL: insert into ACT_GE_BYTEARRAY(ID_, REV_, NAME_, BYTES_, DEPLOYMENT_ID_, GENERATED_) values (?, 1, ?, ?, ?, ?)
