FWIW, my 'java' output tells me: -jvm is a synonym for the "client" VM [deprecated]
i.e., -jvm == -client I do not know when it was introduced, but it says deprecated in u24. Additionally, I do not think "java -jvm server" makes any sense at all. Looks like a genuine typo/overlook/bug. Do file a JIRA for this, and fix it to use "-client" alone, if I understand what it really means to do if EUID == 0.
