Florian Rapp created DERBY-6492:
-----------------------------------
Summary: ASSERT FAILED: LanguageConnectionContext is null
Key: DERBY-6492
URL: https://issues.apache.org/jira/browse/DERBY-6492
Project: Derby
Issue Type: Bug
Components: JDBC
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:
org.apache.derby.shared.common.sanity.AssertFailure: ASSERT FAILED lcc is null
in activation type class
