Java command with flags runs in bash but not zsh

Question

I'm running into an issue where I'm able to run java with proxy settings in bash but not in zsh.

In order to run the jar, I'm first setting my proxy settings with an env variable:

export JAVA_OPTS="-Dhttp.proxyHost=my.proxy.org -Dhttp.proxyPort=80 -Dhttps.proxyHost=my.proxy.org -Dhttps.proxyPort=80 -DsocksProxyHost=my.proxy.org -DsocksProxyPort=80"

Then I run the jar with the following

java $JAVA_OPTS -jar path/to/file.jar

It runs successfully in bash, but when running through zsh, it isn't able to recognize the proxy settings and it fails when trying to establish a network connection.

Anyone know how I can resolve this to be able to use zsh?

zsh does word splitting differently from bash. I think you need to be explicit that you want to split it. Consider this, which acts like a bash quoted variable

$ export JAVA_OPTS="-Dhttp.proxyHost=my.proxy.org -Dhttp.proxyPort=80 -Dhttps.proxyHost=my.proxy.org -Dhttps.proxyPort=80 -DsocksProxyHost=my.proxy.org -DsocksProxyPort=80"
$ printf ">%s<\n" $JAVA_OPTS
>-Dhttp.proxyHost=my.proxy.org -Dhttp.proxyPort=80 -Dhttps.proxyHost=my.proxy.org -Dhttps.proxyPort=80 -DsocksProxyHost=my.proxy.org -DsocksProxyPort=80<

versus this

$ printf ">%s<\n" ${=JAVA_OPTS}
>-Dhttp.proxyHost=my.proxy.org<
>-Dhttp.proxyPort=80<
>-Dhttps.proxyHost=my.proxy.org<
>-Dhttps.proxyPort=80<
>-DsocksProxyHost=my.proxy.org<
>-DsocksProxyPort=80<
