Steps to run the benchmark:
> > cd JFX_WS/tests/performance/Controls
> ant
> java -Djavafx.animation.fullspeed=true
       -cp "JFX_HOME/rt/lib/ext/jfxrt.jar:./dist/Controls.jar:../FXBenchmark/dist/FXBenchmark.jar:../../../import/benchmarks-2.1.1/benchmarks-2.1.1.jar"
       jrockit.bm.Main controls.bm.TableViewBenchmark -i 3 -wt 5 -tr 15 -mode sort -usePulse true -cells 150 30


The issue is seen at least on Windows7.
