Not much to go on to debug here. @SteveMobile do you want to share more specifics of the use case? This stack trace includes a lot of system stuff which is hard to understand.

djinni_support:146 is a call to jniGetThreadEnv() (inside of a comparison function). If there's inlining involved you might actually be seeing the assert at line 50 here: https://github.com/dropbox/djinni/blob/master/support-lib/jni/djinni_support.cpp#L50

If that's the case, it might occur because JNI_OnLoad() was never called, so the global g_cachedJVM variable was never populated. You might want to verify that you included djinni_main.cpp in your JNI library, or else called djinni::jniInit() from your own JNI_OnLoad function.
