How to make PList 'date' format key start with uppercase

[extraSix]

The Apple mdm documentation shows that profile keys need to start with uppercase, such as RemovalDate (in "date" format). However, plist does not support specifying the key to be converted to string. So I have to use Jackson to convert it as follows： POJO -> Map -> NSObject -> String

public class Profile {
    @JsonProperty("RemovalDate")
    private Date removalDate;
}

Not: POJO -> NSObject -> String

However, the 'RemovalDate' in the Map is in String format, not in Date format. It caueses a conversion error. I got:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>RemovalDate</key>
    <string>2023-08-07T07:53:18Z</string>
</dict>
</plist>

It shuold be <date>...</date>:

    <key>RemovalDate</key>
    <date>2023-08-07T07:53:18Z</date>

Is there any solution? Thanks.

In the object you pass to NSObject.fromJavaObject is the RemovalDate a string or a date (java.util.Date)? It must be a date so that it is serialized as <date>...</date>.
