NoSuchMethodError in JNI to Java Exception

Question

I am getting this error:

java.lang.NoSuchMethodError: no non-static method "Ljava/lang/AssertionError;.(Ljava/lang/String;)V"

jclass clazz = env->FindClass( "java/lang/AssertionError" );

env->ThrowNew( clazz, "Test Assertion" );

Note: env is JNIEnv*

Any thoughts? I see that AssertionError exists. I am seeing this on Android Lollipop only. It seems to be fine on android 4.4.2.

Answer 1

Try

jclass clazz = env->FindClass( "java/lang/AssertionError" );

env->ThrowNew( clazz, "Test Assertion" );

I don't know where exceptionClass comes from, but you didn't set it here.

Answer 2

java.lang.AssertionError doesn't have the constructor mentioned in the error message. So you can't use ThrowNew(), which relies on that.

You'll have to construct the exception yourself and use Throw().
