Description

When selecting a CLOB in the deltaImportQuery, the CLOB will not be freed which will cause the Oracle process to use up all memory on the Oracle server.

I'm not very good at java, but I think changes need to be made in FieldReaderDataSource.java. In the getData method, the characterStream from the Clob needs to be copied to a new stream, so the clob can be freed.
