> Key: DERBY-1653
> URL: https://issues.apache.org/jira/browse/DERBY-1653
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.1.3.1
> Environment: Linux (Debian) Kernel 2.6.16
> Reporter: Dipali Sunkersett
>
> One of the component of our project pushes large text (as a binary stream)
> into Derby DB. The other component retrieves these texts in chunks and
> process one text at a time to perform some manipulation. After fetching and
> processing roughly 30K texts, we get an NPE and the whole DB gets corrupt
> after that. We can not connect to that DB again. We use the
> "org.apache.derby.jdbc.EmbeddedDriver" for connecton. The stack trace is as
> below:
> java.lang.NullPointerException
