NullPointerException in BlobDetectionController

[MarcelTUC]

How to reproduce

• Eclipse with DynamicSpotter-Plugin
• create a new project, set up the DynamicSpotter configuration: "workload.experiment.duration: 60", "workload.maxusers: 100".
• As Instrumentation Satellite Adapter use the "DynamicInstrumentationClient"
• As Measurement Satellite Adapter use the "MeasurementClient"
• As workload I am using JMeter.

Start Dynamic Spotter and the exception occurs nearly the end of the test.
