----------------------------------
Summary: FlowBuilderFactoryBean Concurrency Issue
Key: MYFACES-4066
URL: https://issues.apache.org/jira/browse/MYFACES-4066
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 2.2.11
Environment: WebSphere Liberty
Reporter: Bill Lucy
Assignee: Bill Lucy
Priority: Minor
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.
