[jira] [Updated] (DERBY-6492) ASSERT FAILED:
LanguageConnectionContext is null
[ https://issues.apache.org/jira/browse/DERBY-6492?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dag H. Wanvik updated DERBY-6492:

Component/s: (was: JDBC)
Services
> ASSERT FAILED: LanguageConnectionContext is null
> ------------------------------------------------
>
> Key: DERBY-6492
> URL: https://issues.apache.org/jira/browse/DERBY-6492
> Project: Derby
> Issue Type: Bug
> Components: Services
> Affects Versions: 10.10.1.1
> Reporter: Florian Rapp
>
> The LanguageConnectionContext is sometimes null when the system is under heavy load. This seems to be a problem of multithreaded access.
> Our production test got NPE and ArrayIndexOutOfBounds exceptions, we then enabled more logging. We suspect the problem is BaseActivation.initFromContext. The context seems to not be properly initialized, probably due to multithreaded access. The NPE we got could stem from "context.getContextManager()".
> An exception ('ASSERT FAILED lcc is null in activation type class org.apache.derby.exe.aca90748aax0144x7731x56b2x0000131d61d046') occurred in Derby and will be wrapped:
