[jdk11u] Backport the fix of JDK-8180450 to JDK 11?

[Francesco Nigro]

Hi folks,

l'm Francesco Nigro (although known as Franz - so please call me like that
if you wish);
I'm the one referenced at
https://bugs.openjdk.org/browse/JDK-8180450?focusedId=14536886&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-14536886
and mentioned by who has started this whole thread.
Given that I've created the type pollution agent (i.e.
https://github.com/RedHatPerf/type-pollution-agent) I'm in the right and
unique position to list some of the (most) affected product/projects which
reached me out this last 2 years - which I could mention (there are some I
cannot, sadly):
- Cassandra (and DataStax)
- Netty
- Drools & Optaplanner
- Spark
- Hibernate
- Quarkus
- Spring
- Micronaut
- Infinispan
- Camel
- Netflix Zuul
- ...

This just to enforce Andrew's comment
> Several significant Java projects are affected.

"Several" is really a modest term here; we're talking about the biggest
players in the Java Community; which are often "victims" of their own
success and sometimes struggle to get to the very latest JDK version which
fixes it.
My 2c: I'm not suggesting to backport till java 8, but as Aristotele
rightly said "In medio stat virtus" - In the middle stands the truth:
by not backporting in any previous JDK version we let tons of cycles to be
wasted on the cloud/private cloud or, for the projects which can apply
patches to it found by the agent, let them to live with some broken and (at
best) non-idiomatic Java code.

Hope this helps to give a better context of the impact,
Franz
