Problem Description

Non-ASCII characters are not saved correctly in JVM options added using the JVM Options page.

"-Dtest=あああ" is converted to "-Dtest=u3042u3042u3042", this is not expected behavior.

You can also confirm that it is not the expected JVM option value by using the asadmin command:

# /glassfish7/glassfish/bin/asadmin list-jvm-options
--add-opens=java.base/java.io=ALL-UNNAMED
:
-Xmx512m
-Dtest=u3042u3042u3042
-Dorg.glassfish.gmbal.no.multipleUpperBoundsException=true
:
-XX:NewRatio=2
Command list-jvm-options executed successfully.

Steps to reproduce

1. access Admin Console.
2. open Configulation > server-config > JVM Settings.
3. open JVM Options.
4. add the JVM option that contain Non-ASCII characters.
5. save clicked.

Impact of Issue

Users cannot create JVM options that contain Non-ASCII characters in Admin GUI, such as directory paths.
