Warn when certain constructor is used

[Remi Forax]

Hi Pietro,
detecting usages of certain API entrypoints is usually done on the bytecode instead of on the source code in the Java world, it's usually easier because the bytecode is more stable than the source code and it has also the advantage to work not only with Java the language but also in Scala, Groovy, Kotlin, etc.

You can use ASM [1] for that, here is an example [2] from stackoverflow.

cheers,
Rémi
