Can't open HPROF file with Eclipse Memory Analyzer

Tags:

Eclipse Memory Analyzer prompts me only with this message: "Invalid HPROF file header".

Stack dump:

    java.io.IOException: Invalid HPROF file header.

The HPROF file was made on a Linux machine.

HAT doesn't work and the IBM HeapAnalyzer is to complicated, but did work.

What can I do to make it work?

I had the same issue. Adding the flag "format=b" fixed the issue. Apparently, Memory Analyzer can only read binary files.
