I was able to get this working only after adding these to all of the cases
in the switch stmt:
```
case "$cmd" in
manager | master) JAVA_OPTS=('-Xmx512m' '-Xms512m' '-XX:+PrintCompilation'
'-XX:+UnlockDiagnosticVMOptions' '-XX:+PrintInlining' "${JAVA_OPTS[@]}") ;;
monitor) JAVA_OPTS=('-Xmx256m' '-Xms256m' '-XX:+PrintCompilation'
'-XX:+UnlockDiagnosticVMOptions' '-XX:+PrintInlining' "${JAVA_OPTS[@]}") ;;
gc) JAVA_OPTS=('-Xmx256m' '-Xms256m' '-XX:+PrintCompilation'
'-XX:+UnlockDiagnosticVMOptions' '-XX:+PrintInlining' "${JAVA_OPTS[@]}") ;;
tserver) JAVA_OPTS=("${JAVA_OPTS[@]}" '-Xmx6G' '-Xms6G'
'-XX:+PrintCompilation' '-XX:+UnlockDiagnosticVMOptions' '-XX:+PrintInlining')
;;
compaction-coordinator) JAVA_OPTS=('-Xmx512m' '-Xms512m'
'-XX:+PrintCompilation' '-XX:+UnlockDiagnosticVMOptions' '-XX:+PrintInlining'
"${JAVA_OPTS[@]}") ;;
compactor) JAVA_OPTS=('-Xmx256m' '-Xms256m' '-XX:+PrintCompilation'
'-XX:+UnlockDiagnosticVMOptions' '-XX:+PrintInlining' "${JAVA_OPTS[@]}") ;;
*) JAVA_OPTS=('-Xmx256m' '-Xms64m' "${JAVA_OPTS[@]}") ;;
esac
```
I also got a different list of hot methods:
```
