      starting from build 3.0-graphics-scrum-80 which is the first build in which multithreaded mode is enabled by default.

      Steps to reproduce the issue:
      > cd JFX_WS/tests/performance/WebNodeTestSuite/
      > ant
      > java -cp "JFX_HOME/rt/lib/jfxrt.jar;./dist/WebNodeTestSuite.jar;../FXBenchmark/dist/FXBenchmark.jar;../../../import/benchmarks-2.1.1/benchmarks-2.1.1.jar"
        jrockit.bm.Main webnodetestsuite.bm.GUIMark2Benchmark -i 10 -tr 10 -wt 5 -resource guimark2-vector.html


      The issue seems to be not reproduced in case multithreaded mode is disabled.
      At least running the benchmark with -Dquantum.multithreaded=false doesn't fail.
