-----------------------------------
Summary: [DS] Config updates may be missed
Key: FELIX-5264
URL: https://issues.apache.org/jira/browse/FELIX-5264
Project: Felix
Issue Type: Bug
Components: Declarative Services (SCR)
Affects Versions: scr-2.0.2
Reporter: David Jencks
Assignee: David Jencks
If two threads are trying to activate a component concurrently, it's possible
that one enters validateDependencyManagers, determines that a dependency is
missing (so it thinks state should be unsatisfied), then wait, and the other
thread the missing dependency arrives and activates the component, then the
first thread resumes and sets m_satisfied to false. So there's a fully
activated component with m_satisfied false. When a configuration update comes
in it resets the target filters but then tries to activate the component....
which does nothing as it's already activated. So the configuration update does
not get applied.
