Unchecked Null Dereference might cause Null Pointer Exception
Summary
In file SimpleDateFormatObjectDescription.java, line 117, format is assigned from the returned value of super.createObject() method. The code of BeanObjectDescription.createObject() (super.createObject()) suggests that the method might return null in case of any exception. But the returned value is not checked for null in SimpleDateFormatObjectDescription.createObject() method. This may cause Null Pointer exception as in line 119 and 122, applyPattern() and applyLocalizedPattern() methods are called on format.
The static analysis tool was ran on jcommon version: v1.0.23
