----------------------------------------
I tried the attached repro in trunk in *embedded mode* and got error there too
but not a null pointer exception

> Key: DERBY-1599
> URL: https://issues.apache.org/jira/browse/DERBY-1599
> Project: Derby
> Issue Type: Bug
> Components: JDBC, Network Client
> Affects Versions: 10.1.3.1, 10.2.1.6
> Reporter: Knut Anders Hatlen
> Priority: Minor
> Attachments: Repro.java
>
>
> If you create a clob value with one of the ResultSet.updateXXX methods that
> take a stream or a reader, and retrieve that value with ResultSet.getClob(),
> a NullPointerException will be thrown when getSubString() is called on the
> returned Clob object. This happens with the network client driver, and it has
> been observed on Derby 10.1.3.1 and trunk.
> Exception in thread "main" java.lang.NullPointerException
