Hello,
I am usint VTune 2013 update 3 to profile some java application.
Unfortunately, everytime i do, just when the profiled application is going to finish VTunes reports a Segmentation fault in libabstract.so
This does not happen when i debug one of the sample C++ programs. But it deos happen even if i try to profile just "java -version".
I'm using java version "1.7.0_06"
Java(TM) SE Runtime Environment (build 1.7.0_06-b24)
Java HotSpot(TM) 64-Bit Server VM (build 23.2-b09, mixed mode)
Does anyone knows what could be the problem?

I cannot reproduce this problem by using latest VTune(XE) Amplifier XE 2013 Update 3, and Java 1.7.0 Update 11.

For me it only happens when i am using the GUI. I tried with the command line and it passed fine also on my machine.
It also happens with 1.7.0_11.
Yes i am on linux (3.6.11-1.fc17.x86_64)
To reproduce:
- Launch amplxe-gui
- File, New, Project, i named it test2, Create Project
- Application: /path/to/jdk/bin/java (for me /usr/java/jdk1.7.0_11/bin/java)
- Application parameters: -version
- Check allow multiple runs
- All other left to their default value
- OK
- Right-click on the project, New Analysis
- General Exploration under Sandy Bridge / Ivy Bridge
- Check "collect stakcs"
- Start
- A dialog opens : Intel VTune Amplifier experianced an unexpected error...

This is a valuable report, I can reproduce this in command line:
# amplxe-cl -collect snb-general-exploration -knob enable-stack-collection=true -allow-multiple-runs -- /home/peter/jdk1.7.0_11/bin/java -version
Segementation fault,
However if you remove "-allow-mutiple-runs" option, it works. (as a workaround)
This should be a bug in the tool, need to report dev team.
Thank you to let me know this, I will keep to update - if the problem is resolved.

Thank you very much.
Indeed since my last post i noticed that both -knob enable-stack-collection=true and -allow-multiple-runs are needed to reproduce.

Final I got info that option "-allow-multiple-runs" mode does not support call stack collection.
This is not the Java specific issue. I wrote a KB to describe this more detail.
