Subject [jira] Updated: (DERBY-3746) java.sql.SQLException: The exception 'java.lang.NullPointerException' was thrown while evaluating an expression.
Date Fri, 03 Jul 2009 16:00:48 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3746?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Knut Anders Hatlen updated DERBY-3746:
--------------------------------------

               Urgency: Normal  (was: Urgent)
    Bug behavior facts: [Seen in production]

Triaged for 10.5.2.

NPE on the same code location has also been reported in DERBY-3524 and DERBY-4167.

If the stack trace above really is the culprit, it means that we evict an item from the container
cache while it's still in use. Since items are evicted, I assume the number of tables/indexes
in the query mix is fairly high. Default container cache size is 100.

> java.sql.SQLException: The exception 'java.lang.NullPointerException' was thrown while
evaluating an expression.

> 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.
