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

Yes, it does mean
that the next version will need Java 11 (at least for stand-alone).
We need to write
some instructions as to how to get a suitable JVM.

Perhaps someone
could try out these options and write something up (for Windows, Linux
or Mac):
using an existing
system JVM - does MAT find it if it is on path or is -vm option needed.
https://adoptopenjdk.net/
https://adoptium.net/
- no releases yet
point to a JRE in a recent Eclipse installation
install Memory
Analyzer 1.12 into a recent Eclipse installation
install Memory
Analyzer 1.12 into an older version Eclipse installation (may have security
vulnerabilities)
install Memory
Analyzer 1.12 into a Memory Analyzer 1.11 stand-alone version (may have
security vulnerabilities)
something else?

Edit MemoryAnalyzer.ini
with -vm to point to the requred VM

Hey Andrew, Great
job as always! So does this mean the next version will require Java 11
to run?

I've contributed the latest Memory Analyzer 1.12 build to SimRel for inclusion

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.
