Отклонение класса, поскольку он не прошел проверку времени компиляции

Я пытаюсь интегрировать curve25519-java из openwhispersystems в свое приложение для Android и компилировать его с помощью API 23 (Marshmallow). При использовании не родного кода я получаю это исключение во время выполнения:
java.lang.VerifyError: Rejecting class org.whispersystems.curve25519.java.fe_mul because it failed compile-time verification (declaration of 'org.whispersystems.curve25519.java.fe_mul' appears in /data/app/com.fenritz.safecam-1/base.apk)

Это исключение выбрасывается из-за слишком большого количества переменных в одном методе. Простое разделение на два метода устраняет проблему. Вот исправление:
package org.whispersystems.curve25519.java;
public class fe_mul {
//CONVERT #include "fe.h"
//CONVERT #include "long.h"
/*
h = f * g
Can overlap h with f or g.
Preconditions:
|f| bounded by 1.65*2^26,1.65*2^25,1.65*2^26,1.65*2^25,etc.
|g| bounded by 1.65*2^26,1.65*2^25,1.65*2^26,1.65*2^25,etc.
Postconditions:
|h| bounded by 1.01*2^25,1.01*2^24,1.01*2^25,1.01*2^24,etc.
*/
/*
Notes on implementation strategy:
Using schoolbook multiplication.
Karatsuba would save a little in some cost models.
Most multiplications by 2 and 19 are 32-bit precomputations;
cheaper than 64-bit postcomputations.
There is one remaining multiplication by 19 in the carry chain;
one *19 precomputation can be merged into this,
but the resulting data flow is considerably less clean.
There are 12 carries below.
10 of them are 2-way parallelizable and vectorizable.
Can get away with 11 carries, but then data flow is much deeper.
With tighter constraints on inputs can squeeze carries into int32.

Эй, Алекс, я думаю, что это решение вашей проблемы. Захват исключений из синхронизированного блока выходит из строя во время выполнения со следующим исключением: Отклонение класса fr.inra.arttest.MyClass, поскольку он не прошел проверку времени компиляции. Поэтому проверьте все вызовы на синхронизацию. Также вы можете узнать больше об этой проблеме из этой ошибки. https://code.google.com/p/android/issues/detail?id=80961.
Надеюсь, поможет !
