Rejecting class because it failed compile-time verification

问题:

I am trying to integrate curve25519-java from openwhispersystems into my Android app and compiling it with API 23 (Marshmallow). When using non native code I get this runtime exception:

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)       at org.whispersystems.curve25519.java.ge_madd.ge_madd(ge_madd.java:65)       at org.whispersystems.curve25519.java.ge_scalarmult_base.ge_scalarmult_base(ge_scalarmult_base.java:96)       at org.whispersystems.curve25519.java.curve_sigs.curve25519_keygen(curve_sigs.java:30)       at org.whispersystems.curve25519.BaseJavaCurve25519Provider.generatePublicKey(BaseJavaCurve25519Provider.java:50)       at org.whispersystems.curve25519.JavaCurve25519Provider.generatePublicKey(JavaCurve25519Provider.java:8)       at org.whispersystems.curve25519.Curve25519.generateKeyPair(Curve25519.java:70)       at com.fenritz.safecam.SafeCameraActivity.onCreate(SafeCameraActivity.java:105)       at android.app.Activity.performCreate(Activity.java:6237)       at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1107)       at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2369)       at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2476)       at android.app.ActivityThread.-wrap11(ActivityThread.java)       at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1344)       at android.os.Handler.dispatchMessage(Handler.java:102)       at android.os.Looper.loop(Looper.java:148)       at android.app.ActivityThread.main(ActivityThread.java:5417)       at java.lang.reflect.Method.invoke(Native Method)       at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726)       at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616)

Any ideas how why it's being rejected and how can I fix this.

回答1:

This exception is thrown because of too many variable in single method. Just dividing it to two method fixes the issue. Here is the fix:

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. */  private static long[] fe_mul1(int[] f,int[] g){   int f0 = f[0];   int f1 = f[1];   int f2 = f[2];   int f3 = f[3];   int f4 = f[4];

Hey Alex i think this is the solution to your issue. Catching exceptions from a synchronized block fails at run time with the following exception:Rejecting class fr.inra.arttest.MyClass because it failed compile-time verification. So check around any calls to synchronized. Also you can read more about the issue from this google bug post. https://code.google.com/p/android/issues/detail?id=80961.

Hope it helps !
