> Clustered servlet test results are not accurately reported
> ----------------------------------------------------------
>
> Key: CACTUS-60
> URL: http://nagoya.apache.org/jira/browse/CACTUS-60
> Project: Cactus
> Type: Bug
> Components: Framework
> Versions: 1.5-beta1
> Environment: Operating System: Windows XP
> Platform: PC
> Reporter: John Kristian
> Fix For: 1.7
> Attachments: log.txt
>
> If a servlet test suite is deployed to multiple servlet containers in a
> cluster, and invoked by HTTP requests via a load balancer that does round-robin
> or similar routing of HTTP requests that have no session cookies, test results
> are not accurately reported. Initially, tests are reported to have failed
> (inaccurately); at this time, exceptions similar to the one below will be
> thrown in some (not all) servers. Later, the results of one test may be
> attributed (inaccurately) to other subsequent tests.
> The problem does not occur in a non-cluster configuration, nor in a cluster
> with only one server up.
> I'm using jakarta-cactus-13-1.5-beta1, with WebLogic 8.1 SP1 on Windows XP.
