    Description

      There is a (small) chance of ConcurrentModificationException when creating routes dynamically.

      java.util.ConcurrentModificationException
  at java.util.LinkedHashMap$LinkedHashIterator.nextEntry(LinkedHashMap.java:373)
  at java.util.LinkedHashMap$KeyIterator.next(LinkedHashMap.java:384)
  at java.util.AbstractCollection.toArray(AbstractCollection.java:124)
  at java.util.ArrayList.<init>(ArrayList.java:131)
  at org.apache.camel.impl.DefaultCamelContext.getRoutes(DefaultCamelContext.java:650)
  at org.apache.camel.impl.DefaultCamelContext.getRoute(DefaultCamelContext.java:655)

      The cause is that if you happen to be calling getRoute at the same time you are creating a new route then the internals of new ArrayList call collection.toArray which throws the error.
