Holger Rehn commented on DERBY-6681:
------------------------------------
The mentioned bug seems similar but comparing the stack traces I'd guess it is
caused by a different problem (or at least Derby changed a lot since then, in
"my" case Derby seems to first buffer data internally but then doesn't re-use
that buffer).
> Cannot update BLOB/CLOB values in multiple rows simultaneously
> --------------------------------------------------------------
>
> Key: DERBY-6681
> URL: https://issues.apache.org/jira/browse/DERBY-6681
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.9.1.0, 10.10.2.0
> Reporter: Holger Rehn
> Priority: Blocker
> Attachments: MultiLOB.java
>
>
> When trying to execute a single command to update multiple rows with a new
> BLOB/CLOB value, an exception is thrown because Derby tries to read the data
> stream once for every value/row to update.
