It just means that we reviewed it in the 10.5.2 bug triage and made sure that
the bug meta data (component, priority, urgency, affect version, etc...) had
sensible values.

> Key: DERBY-3746
> URL: https://issues.apache.org/jira/browse/DERBY-3746
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.3.1.4
> Environment: SUSE LINUX 10, Embedded Derby
> Reporter: vibhuti gupta
>
> Hi
>
> Following exception occurs while running our application with embedded derby
> database. The application uses multithreading. This exception occurs while
> insert query is executed. The insert query is run using JDBC:
>
> insert into sign (sign, month, day, offset, digest) values (?,?,?,?,?).
>
> The table for which insert query is fired is:
>
> create table sign(ID INTEGER NOT NULL GENERATED ALWAYS AS IDENTITY PRIMARY
> KEY, sign varchar(32), month char(6) not null, day char(2) not null, offset
> bigint not null, digest varchar(32) for bit data not null)
>
> There are multiple threads inserting data in database. I tried to search a
> lot on net but could not find any solution. We're using derby 10.3.1.4. Not
> sure about the root cause. It will be great if anybody provides some solution
> because it is creating lot of problems in our application.
