             Summary: CMISDateUtil.m not thread-safe
                 Key: CMIS-731
                 URL: https://issues.apache.org/jira/browse/CMIS-731
             Project: Chemistry
          Issue Type: Bug
          Components: objectivecmis
    Affects Versions: ObjectiveCMIS 0.2
            Reporter: Mike Hatfield


CMISDateUtil causes problems in multi-threaded environments, e.g. when parsing 
responses from requests using parallel NSOperations.

Problem 1:
NSDateFormatters are documented by Apple to be non-thread safe. The util class 
create a single, static instance which is reused across threads. This needs to 
be refactored.

Problem 2:
The dateFromString: method creates a static NSCalendar instance. This has 
similar problems to the NSDateFormatter above when exposed to a multi-threaded 
environment.
