I’m writing a java program which makes extensive use of native methods and JNI implemented in C++. On the C++ side, I have a local reference to a
jarray which I would like to convert to a global reference. Simple, I think: call
env->NewGlobalRef(array_ref). And, indeed, this works — but the result is a
jobject, not a
jarray. Is it safe to downcast this back to a
jarray? If not, can I recover a
jarray from it? Note that I’m in C++, where these are not just typedefs of each other.
