Description

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.
