The jmap utility currently uses the attach API to implement the -dump option. It might be good to extend jmap so that it uses the same mechanism for -histo (and maybe -heap). This will make the utilities more usable for running applications on Solaris/Linux. Also it means that the options will become available on Windows.
At this time there is little motive to change the -permstat and -finalizerinfo options. If needed, the developer can obtain a heap dump and use jhat/OQL to do more powerful queries. Over time (post-mustang) we can look to update these other options too.
Also, output from jmap options contains a typo.
System.out.println(" jmap [option] [server_id@]<remote server IP or hostname>");
System.out.println(" (to connect to remove debug server)");
remove needs to be remote :)
