Description

Our Jenkins build job occasionally fails with 

java.util.ConcurrentModificationExceptionjava.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(ArrayList.java:911) at java.util.ArrayList$Itr.next(ArrayList.java:861) at org.apache.ivy.util.MessageLoggerHelper.sumupProblems(MessageLoggerHelper.java:45) at org.apache.ivy.util.MessageLoggerEngine.sumupProblems(MessageLoggerEngine.java:136) at org.apache.ivy.util.Message.sumupProblems(Message.java:143) at org.apache.ivy.core.resolve.ResolveEngine.resolve(ResolveEngine.java:347) at org.apache.ivy.Ivy.resolve(Ivy.java:523)

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