Hi , I had recently installed OpenJDK 11.0.18 in one of the Windows FTP server and configured it to the RA FTP Agent . After the change, I could see all the RA FTP jobs copying files from / to MVS (Mainframe) platform failed with below error in the job log report. I had to rollback the change the allow the agent to run on jre1.8.0_111. I would like to know if anyone had faced such issues and what is the workaround/fix Job Report: sun.security.ssl.SSLSocketImpl.getHost() com.uc4.ftpjob.DataTransferException: Source file does not exist: 'filename', can't open file.
