webMethods Knowlegebase : pub.date:dateTimeFormat results in [ISS.0086.9189] Invalid date pattern or input error (1792867)

Problem

Environment has IS 9.8 Core Fix 19 installed.

User performing a date time conversion using the inbuilt service pub.date:dateTimeFormat.

The input to the service is of format 2018-06-20T14:18:28-04:00.

The code is using currentPattern as yyyy-MM-dd'T'HH:mm:ssZ and newPattern as MM/dd/yyyy.

Conversion works properly in webMethods v7.1.2, but getting below error in webMethods v9.8:

"com.wm.app.b2b.server.ServiceException: [ISS.0086.9189] Invalid date pattern or input."

Tested this on an v9.8 server with below inputs:

inString 2018-06-20T14:18:28-04:00

currentPattern yyyy-MM-dd'T'HH:mm:ssZ

newPattern MM/dd/yyyy

After executing, see below error and wanting to use currentPattern as yyyy-MM-dd'T'HH:mm:ssZ:

"Could not run 'dateTimeFormat'
