----------------------------------

             Summary: ConcurrentModificationException in 
MessageLoggerHelper.sumupProblems
                 Key: IVY-1628
                 URL: https://issues.apache.org/jira/browse/IVY-1628
             Project: Ivy
          Issue Type: Bug
          Components: Ant
         Environment: Groovy 2.4.12
            Reporter: Monroe Walker


Our Jenkins build job occasionally fails with 
{code:java}

{code}
It seems this must be due to a warning / error being logged while 
`sumupProblems` is printing the captured warning/errors.
