Class TransformSafeLogger

java.lang.Object

io.opentelemetry.javaagent.tooling.TransformSafeLogger

public final class TransformSafeLogger
extends Object

Debug logging that is performed under class file transform needs to use this class, because gradle deadlocks sporadically under the following sequence:

Gradle triggers a class to load while it is holding a lock

Class file transform occurs (under this lock) and the agent writes to System.out

(Because gradle hijacks System.out), gradle is called from inside of the class file transform

Gradle tries to grab a different lock during it's implementation of System.out
