Getting following error when trying to apply the UpdateLog4j patch on AIX server:
$ ./update.sh
Check that we are in a directory that resembles the ESP dSeries Workload Automation server directory
./update.sh[32]: Current_Release=${wade_version:0:4}: bad substitution
Release : 12.2
Component : CA WORKLOAD AUTOMATION DE (DSERIES)
This problem is reproducible only in AIX.
