[pjfanning]

Check for type pollution - can have a major performance impact. Basically, Java Runtime up to v23 has an issue in a secondary cache used internally to track results of instanceof checks.

https://bugs.openjdk.org/browse/JDK-8180450

FasterXML/jackson-databind#4848

See the micronaut utility mentioned in the issue description.

It may also be useful to check pekko-http.
