We could certainly turn the fields into methods.

Since line.separator is the most popular system property,
and other system properties like
java.home have vague security implications
that would suggest they must be protected by
a security manager, we might consider just
making the one system property available.
Perhaps very simply

String System.lineSeparator()?

or we could put it into

String File.lineSeparator()
