JNI ERROR (app bug): global reference table overflow (max=51200)

Question

问题遇到的现象和发生背景

Android项目中包含JNI，运行时间长的话会报错：JNI ERROR (app bug): global reference table overflow (max=51200)
然后程序崩溃，请问各位这个应该怎么解决呢？

问题相关代码，请勿粘贴截图

#ifdef ANDROID
jobject NativeByteBuffer::getJavaByteBuffer() {
if (javaByteBuffer == nullptr && javaVm != nullptr) {
JNIEnv *env = 0;
if (javaVm->GetEnv((void **) &env, JNI_VERSION_1_6) != JNI_OK) {
if (LOGS_ENABLED) DEBUG_E("can't get jnienv");
exit(1);
}
javaByteBuffer = env->NewDirectByteBuffer(buffer, _capacity);
if (javaByteBuffer == nullptr) {
if (LOGS_ENABLED) DEBUG_E("can't allocate NativeByteBuffer buffer");
exit(1);
}
jobject globalRef = env->NewGlobalRef(javaByteBuffer);
env->DeleteLocalRef(javaByteBuffer);
javaByteBuffer = globalRef;
}
return javaByteBuffer;
}

我的解答思路和尝试过的方法

我想要达到的结果

Answer 1

javaByteBuffer = env->NewDirectByteBuffer(buffer, _capacity);
是不是这里的buffer没有释放导致的内存溢出？
