Type Pollution JUnit tests

Description

Hi, thanks to Micronaut folks, as you can see in FasterXML/jackson-databind#4848: they create an awesome way to verify that type pollution behaviours are under control - and they further improve the work I've done on the type pollution agent, to work with some quirks of the JVM.
I think we could use a similar approach (and use the same agent) to do the same - so we can help in case us or other third party library prove to be affected by this scalability issue, since its fix in JDK 23 will take some.

Very cool!

The only issue I see with this approach is that soon we will have to configure Maven Surefire to allow agent attach, in a similar was as shown here

I see in the PR they have done it - I think it is feasible WDYT?

[geoand]

Yeah, it should be doable
