Environment

RA Solution: FtpAgent 4.1.0

RA CORE 12.3.9 and 12.3.9 HF2

JRE: '1.8.0_112'

 

 

Cause

Customer should no longer use elder JRE  (Java 1.8.0_112)

Resolution

The TLS verification is ensured by Java and since version Kit 8, Update 112 (2016) a lots of improvement were introduced regarding java and security features (TLS version 1.2)..

Refer therefore to : https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8192045

It is recommended for now to upgrade the  JRE./ JKD to a more recent version (for example Openjkd 11 from Adopt).

This should help to get rid of this kind of NullpointerException in the FTP JOB Report.
