NullPointerException freeing temporary CLOB

[Steve]

Hi All,
Can someone tell me why I might see the following:

StackTrace:
java.lang.NullP ointerException
at oracle.sql.LobP lsqlUtil.plsql_ freeTemporaryLo b(LobPlsqlUtil. java:1378)
at oracle.jdbc.dba ccess.DBAccess. freeTemporaryLo b(DBAccess.java :1013)
at oracle.sql.LobD BAccessImpl.fre eTemporary(LobD BAccessImpl.jav a:247)
at oracle.sql.CLOB .freeTemporary( CLOB.java:568)


This is with Oracle 9.2

Thanks
