Property Form
Sandboxed/Safe Properties
Shows properties from the AWT toolkit and System that are considered safe by the plug-in. Also includes other defined properties.
The toolkit will be checked before
System properties, since any property which is either restricted
or not defined on calling System.getProperty(String)
will cause a security exception in a sandboxed applet. For that reason,
the sandboxed applet should not report 'null' ever, but instead
'unknown' to indicate it is unable to determine if the property exists.
Trusted/All Properties
Shows any properties from the AWT toolkit, System and environment that are defined. Returns 'null' if not found. Also includes other defined properties
Defined Properties
The following properties are also defined.
default_locale-Locale.getDefault().toString(). This is available to sandboxed apps. though the equivalent information to construct it fromuser.language&user.countryis restricted.display_mode- Summary of the defaultDisplayMode. This is included because it tells us the screen size (rate, bitdepth), which is handy to know when dealing with full-screen rendering.

Environment Properties
The map returned by
System.getenv()
usually contains information more specific to
the local machine and OS, and less so to Java applications,
but can also reveal some interesting information if you know
what to look for.
