> Under high load when the timing is just right our camel routes are getting
> ConcurrentModificationExceptions. We have tracked this down to
> NormalizedMessageImpl.java in servicemix-core. Specifically in the
> createPropertiesMap method on line 295. There's a comment that Normalized
> exchanges do not need to be thread-safe but we are definitely seeing issues
> with this. We changed the use of HashMap to ConcurrentHashMap and do not see
> the problem anymore.
