java.lang.UnsatisfiedLinkError: could not get native definition for type POINTER

[florianmutter]

After updating to 1.7.0 from 0.115.0 we get the following error on startup of our services:

This is a kotlin service using gradle. The base image we run on is openjdk:17-jdk-bullseye. This is the output of uname -a:

Linux example-7c84f9446c-qfkwv 5.10.147+ jnr/jnr-ffi#1 SMP Thu Nov 10 10:14:30 UTC 2022 x86_64 GNU/Linux

This sounds related to jnr/jffi#138

We upgraded jnr_unixsocket from 0.28 to 0.38.17 between those releases of the Java tracer

[mcculls]

Another possibility is that the recent ddtrot repackaging/shading is confusing JNI - that could be more likely as Foreign.getVersion() is a native method - we'll try to recreate this locally and confirm

[mcculls]

Recreated and fixed in #4779 which will be available in 1.9.0 (expected soon)
