"Not a HPROF heap dump" with IBM .dmp on v1.14.0 [message #1860285]

Hi,

We're getting the following with a .dmp file on MAT v1.14.0 using Java 20.

Error opening heap dump 'core.20230630.180859.30409.0001.dmp'. Check the error log for further details.
Error opening heap dump 'core.20230630.180859.30409.0001.dmp'. Check the error log for further details.
Not a HPROF heap dump (java.io.IOException)
Not a HPROF heap dump

Zipping up the .dmp file did not help any.

Thanks,
--Erik Ostermueller
