---------------------------------------
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
