>
> org.apache.ignite.internal.util.tostring.GridToStringBuilder#classCache
> implemented as
> ordinal HashMap with all operations syncronised by one ReadWriteLock.
> this can trigger high contention as this class widely used in toString()
> methods.
> For instance it shoots when DEBUG or TRACE logs are enabled as count of
> toString() invocations increases in this case extremely.
> We need to use ConcurrentHashMap instead and avoid global locks.
