STEPS TO REPRODUCE
1. Perfom a headless build.
2. install the eclipse plugin.
3. Prepare a core-image-sato-sdk qemux86 image with tools-profile as EXTRA_IMAGE_FEATURES.
4. After step 3 is done, launch the qemux86 within console
5. launch the systemtap tool and fill in all the details. as a systemtap script, use the following one: 

[yocto@localhost 703-3]$ cat trac.stp 
probe syscall.open
{
        printf ("%s(%d) open (%s)\n", execname(), pid(), argstr)
}

probe timer.ms(4000) # after 4 seconds
{
        exit ()
}
[yocto@localhost 703-3]


6. Press ok 

EXPECTED RESULTS
6. the systemtap tool connects to the qemu image and provides an output in eclipse

ACTUAL RESULT
6. A popup window appears without text in it. 
IN the eclipse console I have the followin error:
