STCAL: Static DateFormat (STCAL_STATIC_SIMPLE_DATE_FORMAT_INSTANCE)
As the JavaDoc states, DateFormats are inherently unsafe for multithreaded use. Sharing a single instance across thread boundaries without proper synchronization will result in erratic behavior of the application.
You may also experience serialization problems.
Using an instance field is recommended.
