I want to add -a (all) option to JSnap because JSnap is very useful to analyze core image.
Currently, JSnap can show PerfDataEntry which namespace is java.* or com.sun.* . We can use jcmd with PerfCounter.print when we want to attach live process, however, as JDK-6224040 shows, we have to use JSnap. In terms of core image analysis, -a option is very useful for troubleshooting. I uploaded a webrev for this enhancement. Could you review it? http://cr.openjdk.java.net/~ysuenaga/JDK-8148659/webrev.00/ I'm jdk9 committer, however I cannot access JPRT. So I need a sponsor. Thanks, Yasumasa
