The test does create Text node with DropShadow effect and few controls which bound to DropShadow effect properties
on every second iteration.
The intend of this test was to reproduce memory leak found by Ensemble2AutoTest.
However, the test fails with NullPointerException before reaching OOM.

Steps to run the test:
> java -cp "..." -Xms16m -Xmx16m EffectMemTest
