[jira] [Created] (CONFIGURATION-530) AbstractFileConfiguration.getProperty(String key) locking causes thread hault

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

             Summary: AbstractFileConfiguration.getProperty(String key) locking causes thread hault
                 Key: CONFIGURATION-530
                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-530
             Project: Commons Configuration
          Issue Type: Bug
          Components: File reloading
    Affects Versions: 1.9
            Reporter: yair ogen
            Priority: Critical


Every call to getProperty causes a lock (related to the reload functionality). In a near real-time system where we have many concurrent threads this affects heavily on the application TPS. 

Possible solution will be: getProperty only returns current value. Reload when needed occurs in a background thread that updates the in-memory map (perhaps by using CopyOnWrite collections?).
