Duncan Jones updated LANG-996:
------------------------------

    Description: 
It seems that {{FastDateFormat}} is case sensitive. But it claims to be mostly 
compatible with {{SimpleDateFormat}} which is not.

For example, this throws a {{ParseException}}:

{code:java}
FastDateFormat.getInstance("dd-MMM-yyyy").parse("01-jan-2000");
{code}

But these do not:

{code:java}
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy");
sdf.parse("01-jan-2000");
DateUtils.parse("01-jan-2000", "dd-MMM-yyyy");
{code}
