> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.1.3.1
> Environment: Linux (Debian) Kernel 2.6.16
> Reporter: Dipali Sunkersett
> Priority: Critical

> 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:
