/*
* The purpose of this class is to satisfy package structure requirements while enabling VM update modes.
* The non-debug centric VMCacheManager and VMCache live under org.eclipse.dd.dsf.*. The debug data view
* caches (VMCacheRefreshAlways/Manual/OnBreak) live under org.eclipse.dd.dsf.debug.* because of their
* awareness of debug specific events. There is a need to instantiate a default (always) cache on view
* startup. AbstractDMVMProviderWithCache would be a good place to accomplish this task, but like the
* VMCacheManager, this class cannot access the *dsf.debug* VMCacheRefreshAlways. AbstractDebugDMVMProviderWithCache
* is meant to solve this problem.
