DateFormat output changed between versions.

ADDITIONAL SYSTEM INFORMATION :
Mac or Linux, Java 8 and Java 11

A DESCRIPTION OF THE PROBLEM :
When using DateFormat.format the timezone is output differently depending on Java version

REGRESSION : Last worked in version 11.0.2

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the supplied class with Java 8 and Java 11


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The output is the same, regardless of versions.
ACTUAL -
The output of Java 8 is "09/08/2001 at 8:46:39 PM CDT"
The output of Java 11 is "09/08/2001 at 8:46:39 PM Central Daylight Time"

CUSTOMER SUBMITTED WORKAROUND :
Haven't implemented a workaround but I imagine a Map<String,String> with the desired vs new versions could be used

FREQUENCY : always
