Do not use java.nio in crashtracking init (premain) by amarziali · Pull Request #11080 · DataDog/dd-trace-java

amarziali · 2026-04-10T15:12:41Z

What Does This Do

Avoid using java.nio in the initialisation part of the crashtracking agent. This because, at this point, initializing java.nio can lead to side effects (deadlocks, premature initialisations, etc..)

Also, the same operations can be done using a regular java.io
