java.lang.OutOfMemoryError occurs in AppServer's Controller
log while retrieving PMI data.  The JVM Heap is full of objects
for com/ibm/ws/pmi/dynamicproxy/PerfPrivateLocal.
Incorrect caching logic caused ever increasing cache size which
would finally lead to a java.lang.OutOfMemoryError.
Problem conclusion
Caching operations of data descriptors in the PMI code have
been corrected to use the proper identifying string.
