Claus Ibsen commented on CAMEL-3275:
------------------------------------
Ah the problem is the {{putAll} method which should be {{synchronized}}. So the
fix should be
from
{code}
public void putAll(Map<? extends String, ?> map) {
{code}
To
{code}
public synchronized void putAll(Map<? extends String, ?> map) {
{code}
> CaseInsensitiveMap should extend ConcurrentHashMap
