Description Andrew Johnson

2018-11-25 16:29:57 EST

Bug 483418 was created to answer a request for:

"b. The Eclipse Memory Analyzer can compare two heapdumps, Run this compare function in command line. "
http://dev.eclipse.org/mhonarc/lists/mat-dev/msg00449.html

Here is another approach which uses the experimental facility in bug 380600 to allow options to be passed to reports.

This defines a hidden query comparing two snapshots, the second specified as Advice.SECONDARY_SNAPSHOT and invokes it as a query, using the new filter type !=0 to remove entries which are the same.
