Knut Anders Hatlen updated DERBY-4224:
--------------------------------------
Component/s: Network Client
Derby Info: [Regression]
Derby Categories: [Embedded/Client difference] (was: [Regression Test
Failure])
Summary: Commit after setAsciiStream() makes execution fail with
the client driver (was: Got SQLException)
Updating the summary with a more accurate description of the problem.
Also flagging this as an embedded/client difference, since the example program
appears to work fine with the embedded driver.

> Key: DERBY-4224
> URL: https://issues.apache.org/jira/browse/DERBY-4224
> Project: Derby
> Issue Type: Bug
> Components: JDBC, Network Client
> Affects Versions: 10.4.2.0
> Reporter: Simon Meng
>
> Got below error message when running a JDBC prolgram with derby. I use Apache
> Derby Network Server - 10.4.2.0 - (689064). The same program works fine with
> another version Apache Derby Network Server - 10.2.2.0 - (485682). It looks
> like there is a regression between the two versions.
> Exception in thread "main" java.sql.SQLException: You cannot invoke other
> java.sql.Clob/java.sql.Blob methods after calling the free() method or after
> the Blob/Clob's transaction has been committed or rolled back.
