Inside curve25519-jni.c, the following code is used to throw an AssertionError when certain signature functions fail:
(*env)->ThrowNew(env, (*env)->FindClass(env, "java/lang/AssertionError"), "Signature failed!");
This works on older versions of Android (e.g. KitKat), however it causes a NoSuchMethodException on newer versions of Android (e.g. Lollipop). This is because AssertionError does not actually have a constructor that takes a String. (Just one that takes an Object, which it internally converts to a string.)
A simple fix would be to pick a different exception that has a String-only constructor. A more complicated fix would be to construct the AssertionError object manually, prior to throwing it.
