==============
SWFT-2493
SWIFT plugin 5.16 has incorrect field 35B behavior.

SWFT-2494
SWIFT Parse encountered issue when parsing MT103 message which only contains tag 111 and 121 in section 3 User Header

Configuration Instruction:
A new tra property java.property.SWIFT.UserHeader.FieldRequired has been introduced by this hotfix, and needs to be set in tra file to take effect. When its value is 0 as default, Swift plugin works as before, i.e., it enforces a validation rule that at least one tag out of 103, 113, 108, 119 or 115 must be present in the user header; when its value is 1, the Swift plugin treats all tags as optional in the user header.  

SWFT-2499
Customer encountered "java.lang.NullPointerException at com.tibco.swift2.validate.rules.spec2017.Msg586Rule.evalC14" issue when parsing MT586 message
