Search reasource leaks in Eclipse

here is instruction how is possible find a reason of resources leaks:
1) is necessary to install Sleak plug-in for Eclipse via -> Help -> Insrall New Software -> update site:
http://www.eclipse.org/swt/updates/3.8
2) close Eclipse;
3) from the file eclipse_3.7\plugins\org.eclipse.ui_??.jar copy .options into Eclipse folder and setup:
org.eclipse.ui/debug=true
org.eclipse.ui/trace/graphics=true
4) create eclipse.bat into Eclipse folder:
eclipse.exe -clean -debug
5) use eclipse.bat for eclipse (for HP Studio) start;
6) open the Sleak view: Window -> Show View -> Other ... -> SWT Tools -> Sleak;
now is possible to take snapshot of allocated resources and take a difference between allocated resources - so it will be possible to find a leak reason

P.S.:
main reference to SWT Development Tools:
