By the way, I just tried Karaf 3.0.2 with Java7:
1/ I used dev:dump-create
2/ after uncompress the dump zipfile, I have the heapdump.txt
3/ in jvisualvm, I used "File->Load" with "Heap Dumps (*.hprof,*.*)",
and selected the heapdump.txt
4/ the heapdump opens without problem in jvisualvm
I'm trying with Java8.

Hi guys,
I use Karaf 3.0.2 with java 8_u40 and investigate on a memory leak in
one of our bundles we developed. I created a heap dump using the karaf
command dump-create which is very useful. It created a dump.zip file
containing all the information I need. However, I tried to open the
heapdump.txt with jvisualvm to analyze the memory of our application but
jvisualvm cannot open the dump file. I used a second memory analysis
tool, eclipse memory analyzer and this tool was able to open the dump
file and get the information of the dump … Have you ever tried opening a
memory dump with visualvm, it is the tool I prefer for finding leaks?
Secondly, I like to “ live” monitor memory using jvisualvm and use its
Heap Dump button to create memory dumps when I want to, but when I try
to use this command it doesn’t work and I get the error “cannot take
heap dump for org.apache.main.Main” ? Is there a way to configure karaf
so that I can dump memory through jvisualvm ?
Which tool do you usually use to find memory leaks ?
Thank you.
Regards
Seb
