Problem

-Dkey=value

Value does not allow spaces ?

Resolve

Use an additional array variable ( e.g. X_JAVA_OPTS ) to join with arguments

This way, the value can be allowed to contain spaces.

Thanks

arguments array elements allow spaces, so join e.g. -Dxxx.path=/home/us/app 3.0/lib to arguments is ok !!!
e.g.

arguments=(-Dsun.misc.URLClassPath.disableJarChecking=true $JAVA_OPTS  "-Dxxx.path=/home/us/app 3.0/lib"  -jar "$jarfile" $RUN_ARGS "$@")

e.g.

[[ -f "$PID_FOLDER"/vm.options ]] && source "$PID_FOLDER"/vm.options
if [ -n "$X_JAVA_OPTS" ]; then
  arguments=(-Dsun.misc.URLClassPath.disableJarChecking=true $JAVA_OPTS ${X_JAVA_OPTS[@]} -jar "$jarfile" $RUN_ARGS "$@")
else
 arguments=(-Dsun.misc.URLClassPath.disableJarChecking=true $JAVA_OPTS  -jar "$jarfile" $RUN_ARGS "$@")
fi

before start

declare -p X_JAVA_OPTS > "$PID_FOLDER"/vm.options

Thanks for the report. Unfortunately, handling of spaces in the launch scripts isn't as good as we'd like, but we've yet to identify a way to fix it that's backwards compatible and that we're happy with. Please see https://github.com/spring-projects/spring-boot/issues/19716 and https://github.com/spring-projects/spring-boot/issues/18540 for details. Until those issues are addressed, please use a custom launch script that meets your specific needs.
