> Project: MyFaces Core

> Environment: WebSphere Liberty

> Assignee: Eduardo Breijo

>
> I've come accross a concurrency issue in
> org.apache.myfaces.flow.cdi.FlowBuilderFactoryBean.getFlowDefinitions(). If
> multiple applications (with programmatic flows) are starting up
> simultaneously, it's possible that the two responsible threads can
> concurrently modify the shared object FlowBuilderFactoryBean.flowDefinitions.
> That can result in the flowDefinitions for one of the applications not being
> processed.
> Synchronizing the getFlowDefinitions() method is the simplest fix for this
> issue.
