Reading the public_suffix_list.dat file is modified to be similar to [DomainName.java](https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/sun/security/util/DomainName.java). If the file is not present, `isPublicSuffix()` returns `false`, which is similar to how WebKit ignores the public suffix check when it is disabled.

I verified that the doPrivileged change allows it to work with a security manager. The only issue I now see is related to the log warning.

This should be a single string, so you need to concatenate them.
