             Summary: Configadmin interpolator can run into a StackOverflow
                 Key: FELIX-6619
                 URL: https://issues.apache.org/jira/browse/FELIX-6619
             Project: Felix
          Issue Type: Task
          Components: Configuration Admin
            Reporter: Joerg Hoh



If you have an error in the configuration settings, the interpolator can run into a stack overflow caused by endless recursion.


configuration:
{noformat}
foo = $[env:foo]
{noformat}


{noformat}

{noformat}

We should have a limit how deep this recursion can go.
