[performance][JNI] Game throws JNI exception every frame

When building with 5.2 and 5.2 I see this exception thrown for every frame in the menu, and another JNI exception, not gameanalytics, in game. This causes massive performance drops.

Anyone seen something like this before?

The game runs fine with 5.0.3f p3, no exception at all.
