[mat-dev] Memory Analyzer 1.12 contribution to Eclipse 2021-06 M3

[Andrew Johnson <andrew_johnson@xxxxxxxxxx>]

I've contributed
the latest Memory Analyzer 1.12 build to SimRel for inclusion in Eclipse
2021-06 M3.

Please test the
code at https://www.eclipse.org/mat/snapshotBuilds.php

There is still
time for fixes, 1 week before  Eclipse 2021-06 RC1 and then another
week before  Eclipse 2021-06 RC2, so do report any problems.
https://wiki.eclipse.org/Category:SimRel-2021-06
.
There a few more
things to do - a New and Noteworthy, help for unindexed objects (&
possibly some OQL tidy up) and reviewing the bug list
https://projects.eclipse.org/projects/tools.mat/releases/1.12.0/bugs

Some new features
are:
Enable parsing of compressed files created by OpenJDK >= 15, and also
performance improvements with gzipped HPROF files.
Viewing unindexed
objects from snapshots with discarded objects
Acquire heap dump
improvements

I would like to
build the stand-alone MAT 1.12 against Eclipse 4.20 from Eclipse 2021-06
as then we can pick up some Jetty security fixes. They aren't essential
but using older versions could cause security scans to flag the plugins.
The release 4.20 is not available yet so I've made a guess as to the target
platform. We now have target platform and product files which can be separately
specified in regular builds. The 'mat-promote-release' takes the SimRel
contribution and generates matching binaries; I think it needs parameterising
for the destination location and possibly target platform & product.
