I can't open the zip file.

[c-koell]

Oh sorry @pshipton. I have re-uploaded a new zip file. (2611630.zip)

[pshipton]

I can't extract any information from the core (No JRE). The core is truncated which is likely the reason.

FYI the first warning is because jpackcore should be run on a core file, in order to be able to look at the core in gdb on a different machine from where it was produced.

Warning: native libraries are not available for 2611630.core
Warning: dump file is truncated. Extracted information may be incomplete.

For a list of commands, type "help"; for how to use "help", type "help help"
Available contexts (* = currently selected context) :

Source : file:///home/peter/2611630.core
        *0 : PID: 2611630 : No JRE

Oh that sounds not good. @pshipton Can i do anything here on the machine where the core dump was produced ?

I will close this issue until we have a valid Core Dump

I don't know if it would make a difference, but there is one newer release, 0.48.
