[jira] [Created] (PHOENIX-5685) PDataTypeFactory Singleton is not thread safe

Swaroopa Kadam created PHOENIX-5685:
---------------------------------------

             Summary: PDataTypeFactory Singleton is not thread safe
                 Key: PHOENIX-5685
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5685
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 5.0.0, 4.15.0
            Reporter: Swaroopa Kadam
             Fix For: 5.1.0, 4.15.1, 4.16.0


The singleton class uses lazy initialization of the INSTANCE variable, however, the PDataTypeFactory#getInstance method is not synchronized to be thread-safe. Good to make use of double-checked locking.
