When upgrading to version 9.0.20.200, the Kafka service fails to start when additional JVM environment variables were set previously.

Example locations for setting JVM environment variables affecting this issue (consult your System Administrator if needed)
Unix:
$HOME/ctm_em/etc/em_env_local.*sh files
$HOME startup scripts such as .cshrc, .bash_profile, .profile

Windows:
[EM Install dir]\etc\env file
OS System Environment Variables

Example setup screen output:

If package date shows October then downloading the latest 9.0.20.200 FP on EPD will solve this issue. The correct month on the package date should be November.
