When troubleshooting heap memory size generating heap dumps with command jmap from java bin directory, the generated heap dumps are corrupted and can not be read by Eclipse MAT (third-party tool).
This inhibits troubleshooting of a container crash.

The troubleshooting pattern was to collect heap dumps getting closer to the crash.

Command used is

cmd>jmap dump:format=b,file=heap.hprof <PID>

where PID is the process ID of the container being examined

The error thrown by Eclipse MAT when opening the heap dump is

Failed to open

"Parser found 0 HPROF dumps in file nnnn.hprof. No heap dump index 0 found. See FAQ.2"
