MediaSystemTest benchmarks throws "IllegalStateException: The view has already been closed" when running with j2d pipeline.
The exception seems to be thrown after warmup phase is completed:
# Unit: mediasystemtest.bm.MediaSystemBenchmark
# Starting run at: Mon May 30 23:05:38 PDT 2011
# Running a timed run.
# Duration (per iteration): 180s
# Warmup: 15s
# Iterations: 3
# Threads: 1
*** Fallback to Prism SW pipeline

The issue is reproduced with latest promoted fx2.0-b30 (hudson build #171)
and is observed with both hardware and software pipelines.
