> If the {{readLockCheckInterval}} is greater than or equal to {{readLockTimeout}} when
using {{readLock=changed}}, the consumer never picks up any files.
> So this URI will triggers the behaviour:
> {{file:some-folder?readLock=changed&readLockCheckInterval=1000&readLockTimeout=500}}
> The problem is that {{FileChangedExclusiveReadLockStrategy}} only takes {{readLockTimeout}}
into account. 
> 1. {{FileChangedExclusiveReadLockStrategy}} get the last modified and size of the file.
> 2. It sleeps for the duration configured in {{readLockCheckInterval}}
> 3. Now the timeout configured in {{readLockTimeout}} is exceeded, so {{FileChangedExclusiveReadLockStrategy}}
logs "Cannot acquire read lock within.." and returns false
