Hi Staffan,

Maybe, if the input experience of CLHSDB can be improved. It's awful to
prototype new commands with JavaScript in CLHSDB, because the whole snippet
of script is only allowed to span one single line, using "jseval". If it
can at least
I think current SA/hotspot developers are the best judges. I used to be
part of serviceability team and worked on SA among other things in the
past. AFAIK, SA suspend/resume was never really implemented or worked
properly. If that is still thought to be useful, we may to see if we can
improve
Thanks for the pointer to SA Plugin - didn't know about that. Any idea how
widely used it is?
Thanks for the rest of the feedback as well,

Hi Kris,
SA-Plugin for VisualVM uses HotspotAgent - SA interface provided by
class sun.jvm.hotspot.HotSpotAgent. SA-Plugin uses the attach/detach
functionality provided by this class and it uses other SA classes (e.g.
sun.jvm.hotspot.runtime.*, sun.jvm.hotspot.ui.*) to extract and display
dat
Hi,
SA uses stop-the-world to debug "snapshot" of the process. BugSpot was
supposed to be a SA model where you can pause/resume and keep looking at
different snapshots (as well as use JDI to look at process state). But,
it was never implemented that way. Over the years lot of stuff
accumulate

Hi Staffan,
There's at least another frontend, the SA Plugin for Visual VM. I think it
only uses the BugSpotAgent for attaching/detaching, otherwise it doesn't
use stuff from BugSpot.
Other tools, e.g. jstack -m, jstack -F, jmap -F, etc., are not exactly SA
frontends, but use the SA to implement t

BugSpot - improvement over HSDB ??
