Hi James, 1) all the other -XX options seem to use syntax like -XX:PermSize=256m
... Unless I made a typo in the bug report, "-XX:PermSize=256m" is indeed the correct syntax. 2) is anyone really using XX:PermSize? Google only found it mentioned 3 times. ... Oh absolutely, this option is more common than you think. Not sure what you googled, but when I searched for "XX:PermSize", I found over 14,000 hits! 3) these -XX options are described as "not stable" and ... subject to change without notice. http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp ... Unfortunate that their (somewhat outdated) docs state that, but regardless, this particular option has not changed and is very necessary to get applications using modern libraries such as the Spring Framework or Hibernate to operate for long running applications (such as web server applications). 4) Does using "=256m" allow the JVM to start up for you? ... when I remove the "-XX:PermSize" and the "-XX:MaxPermSize" options, then the java virtual machine (jvm) does indeed startup. However, the lack of these options in place will eventually lead to the early demise (aka: out of memory error) of any large application that performs a lot of classloading (hence the need for setting the permanent generation to a larger setting than the default if not specified ... which I believe is 64 megabytes ... much too small). This leaves anyone trying to use modern java (jdk1.6) on ubuntu without the ability to run large applications.
