'heapdump.xxx.phd'. Not a HPROF heap dump

问题:

The Eclipse Memory Analyser docs say it can open IBM portable heap dump files (*.phd):

However, when I try to open one I get and error:

'heapdump.xxx.phd'. Check the error log for further details.
Not a HPROF heap dump (java.io.IOException)
Not a HPROF heap dump

I've tried both menu options (File > Open Heap Dump) and (File > Open File)

You have to install DTJF in order to read IBM files.
