[jira] Commented: (DERBY-4443) Wrap rollback in exception handlers
in try-catch
[ https://issues.apache.org/jira/browse/DERBY-4443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12778286#action_12778286 ]
Aaron Digulla commented on DERBY-4443:
--------------------------------------
One place where I've seen this is SystemProcedures. Every method in there uses this anti-pattern.
Instead of calling rollback directly, a utility function should be defined which either ignores any exceptions in rollback or, preferred, prints/logs the exception.

> Key: DERBY-4443
> URL: https://issues.apache.org/jira/browse/DERBY-4443
> Project: Derby
> Issue Type: Bug
> Components: Demos/Scripts, Documentation, Eclipse Plug-in, JDBC, Network Client, Network Server, Replication, Services, SQL, Store, Test, Tools
> Affects Versions: 10.5.3.0
> Reporter: Aaron Digulla
>
> Avoid this pattern everywhere:
> }catch(SQLException se){
> //issue a rollback on any errors
> conn.rollback();
> throw se;
> }
> because an error in rollback will shadow the original exception.
