This tool would be awesome if it were made a bit simpler to use. For example, why all that JVM-param-mumbo-jumbo? If Java Virtual VM can attach to a Java VM without any changes in the params, this tool should, too. Also, why two different programs? Why not just add an option "build svg" or something to the main program?
Personally I would've loved to use that tool for a small problem I have right now, but I'm not interested enough to fiddle around with the JVM settings and the filters and so on. Especially if it could've been, as far as I understand it, as simple as starting a tool, selecting the JVM instance in a nice GUI, set some optional options and hit something like "start capture"
