Which folder does Apryse Java SDK extract the embedded native binaries to?

Question:

In recent versions of Apryse SDK for Java, the native binaries for macOS, Windows and Linux are embedded inside the JAR, but that requires them to be extracted somewhere and loaded by the JVM and JNI.

Where does Apryse extract these binaries to?

Answer:

Apryse is extracting them to the folder defined by the java.io.tmpdir environment variable. This Stackoverflow answer goes into a bit more detail about this environment variable.
