This means that the hostname is present in the heap of the JVM process, but I believe that the hostname should be considered confidential data. We should really only get the hostname if the user explicitly requests this.

@jdksjolen , @dholmes-ora
Thanks for comments. We now only get the host name if the user explicitly requests it.
I also added the missing documentation to `java -Xlog:help`.
