bq. but for J9, it sets the variable and doesn't include what's there previousl
Indeed, and as I put in the comment above that line, on the -Xverbosegclog is
required/supported by J9, as far as I could tell from the J9 team. Also this
page which they pointed me at does not indicate any additional parameters are
needed:

bq. The removed line (replaced with the if/else construct) uses parentheses to
combine the old with the new,
You're right. At first I thought that the parentheses don't work because when I
echoed them using {{echo $GC_LOG_OPTS}} it only printed the -verbose:gc. I now
tried {{echo "$\{GC_LOG_OPTS[@]\}"}} and it works. I'll restore that.
