help would be appreciated.

Answer 1

I'm assuming you are only seeing this on Galaxy S5, if not, please let me know.

Based on my research Samsung has done something to the install process (dex2oat etc) or to ART that makes it behave differently from every other manufacturer out there.

For whatever reason, for a given class A any object that is instantiated from a JNI layer is reported as being of a different class compared to an object that is instantiated from plain Java.
This works fine when CheckJNI is disabled because the classes are actually identical, but when CheckJNI is enabled it complains (when debugging this it seems that any class instantiated from the JNI layer on S5 is actually part of a different dexcache -- this is not the case on eg Nexus 5 running L).

TL;DR : CheckJNI seems to malfunction on S5 with Android L. Building the app in release mode disables CheckJNI and everything works as expected.
