ArrayIndexOutOfBoundsException when printing benchmark results

[seelchen]

When using the StatisticsCollectionPass and printing the benchmark results, an ArrayIndexOutOfBoundsException is thrown. I think this happenes because the MeasurementHolder from the StatisticsCollectionPass holds two measurements unlike the other Benchmarks which only hold one measurement. When they are converted into the table for printing, the MeasurementHolder is converted into a list with length 4 which doesn't align with the other lists with length 2.

Do you have an example code that triggers this?
