我尝试在linux机器上运行jstatd jvm监控工具

jboss@hostAddr:/usr/java/jdk1.6.0_18/bin> uname -a
Linux hostAddr 2.6.16.60-0.34-smp #1 SMP Fri Jan 16 14:59:01 UTC 2009 x86_64 x86_64 x86_64 GNU/Linux

使用以下命令:

jstatd -J-Djava.security.policy=~/jstatd.all.policy

jstatd.all.policy内容

grant codebase "file:${java.home}/../lib/tools.jar" {

   permission java.security.AllPermission;

};

不幸的是我得到以下输出:

Could not create remote object
access denied (java.util.PropertyPermission java.rmi.server.ignoreSubClasses write)
java.security.AccessControlException: access denied (java.util.PropertyPermission java.rmi.server.ignoreSubClasses write)
        at java.security.AccessControlContext.checkPermission(AccessControlContext.java:323)
        at java.security.AccessController.checkPermission(AccessController.java:546)
        at java.lang.SecurityManager.checkPermission(SecurityManager.java:532)
        at java.lang.System.setProperty(System.java:725)
        at sun.tools.jstatd.Jstatd.main(Jstatd.java:122)

出于某种原因,jstatd在具有相同命令和策略文件的Windows上成功运行.
