I read on the book; "Professional Apache Tomcat" 1-86100-773-6, Chapter: "3. Tomcat Installation", Section: "Choosing a JVM", Page: 32, of some JVMs having ways to run classes offering memory protection for loaded data, which is of paramount importance when you are running a server.
This is what it says:
"... such as those (JVMs) providing extra high security guarantess (specially security of in-memory data) ..."
They stopped it there, no specifics or further information were given
Is this a purely JVM design thing or a partial|total architectural one in which the OS and other issues might be envolved?
How would such "security of in-memory data" affect speed?
Isn't enough with hardware protection ECC type memory and the OS settings?
