[Valgrind-users] Valgrind with Java/Jna

[myrmidia]

Hi there,

I try to use valgrind with a Java program to detect memory leak within a 'C' library. This 'C' library is access by JNA (Java Native Access : https://jna.dev.java.net) framework...
For information, this program is running on a Virtual Machine (ESX). The linux is a Centos 5.3 and I use the latest available release of Valgrind on default repository !
The JDK/JRE is the latest available release from SUN.

Command line:
valgrind --leak-check=yes java -jar test.jar
Result :
The program ran perfectly but valgrind doesn't detect nothing AND there's some memory leaks in the library ;-((

Command line:
valgrind --trace-children=yes --leak-check=yes java -jar test.jar
Result :
Error occurred during initialization of VM
Unknown x64 processor: SSE2 not supported

The physical processor on the EXS is a Xeon so it supports SSE2 and I've this log on the stderr with '--verbose' option :
Arch and hwcaps: AMD64, amd64-sse3-cx16

Any idea ???

Best regards,

[John Reiser]

Please post the following info from a terminal session running
on the vmware ESX virtual machine:

$ cat /proc/cpuinfo | sed 6q

which gives the cpu family, model, and stepping, such as:
-----
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 107
model name : AMD Athlon(tm) 64 X2 Dual Core Processor
stepping : 2

This is the output...

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Xeon(R) CPU X7350 @ 2.93GHz
stepping : 8

For information, this is exactly the real processor on the ESX !

Best regards,

Valgrind is claiming to be a Core 2 E6600. The CPU in the
real machine and the one provided by ESX is irrelevant.
Strange that your Java VM doesn't want to run on that.

Java VM run on that configuration but there's some inconsistency when I'm using valgrind with/without the '--trace-children' option.

Without this option, I have no output from valgrind (but there was some memory leaks in the 'C' library) AND the program ran perfectly.
With this option, unable to initialize the VM...
