Description

In some situations (e.g., running a certain version of the native client quickstarts) a ClassCastException is thrown inside ExecuteFunction66.run() at line 391 of ExecuteFunction66.java:
final DistributionManager newDM = (DistributionManager) dm;

The variable dm is an instance of the interface org.apache.geode.distributed.internal.DM. The class org.apache.geode.distributed.internal.DistributionManager implements DM but not all implementers of DM extend DistributionManager, e.g., org.apache.geode.distributed.internal.LonerDistributionManager.
