eclipse MAT in headless mode

[Luca Maderna]

thanks Bernd.
In MATfor Win32 in MemoryAnalizer.ini, I have:

     -startup
          plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
     --launcher.library

plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502
     -vmargs
    * -Xmx1024m*

I've tried to modify -Xmx an it seems working.

danke
luca
