Subject [jira] [Created] (CAMEL-8387) File consumer fails to acquire lock if readLockTimeout >= readLockCheckInterval

Christoffer Eide created CAMEL-8387:
---------------------------------------

             Summary: File consumer fails to acquire lock if readLockTimeout >= readLockCheckInterval
                 Key: CAMEL-8387
                 URL: https://issues.apache.org/jira/browse/CAMEL-8387
             Project: Camel
          Issue Type: Bug
            Reporter: Christoffer Eide


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
