b cannot be cast to com.mysql.jdbc.blob_jbpm4.4 部署流程时出现 $Proxy8 cannot be cast to oracle.sql.BLOB...

我原来使用的是mysql部署很正常，把数据库换成oracle 部署时就出现了错误,搞了半天还是不行

Hibernate: insert into jbpm4.JBPM4_LOB (DBVERSION_, BLOB_VALUE_, DBID_) values (?, ?, ?)

java.lang.ClassCastException: $Proxy8 cannot be cast to oracle.sql.BLOB
