java – JNI NewByteArray内存泄漏

jbyteArray jBuff = _env->NewByteArray(b->Length);

我的代码：

static jobject staticArray=0;

System::String^ MyClass::ExecuteJavaMethod(System::Drawing::Bitmap^ bmp)
{
    jnienv *_env;
    System::String^ out;
    unsigned const char * buff;

    int res = jvm->AttachCurrentThread((void **)&_env,NULL);

    if (jvm->GetEnv((void**) &_env,JNI_VERSION_1_6) != JNI_OK)
    {
        return "GetEnv ERROR";
    }

    //save the bitmap in the stream
    MemoryStream^ ms = gcnew MemoryStream();
    bmp->Save(ms,ImageFormat::Bmp);

    //get the bitmap buffer
    array<unsigned char>^b = ms->GetBuffer() ;

    //unmanaged conversion
    buff = GetUnmanaged(b,b->Length);


    //fill the buffer
    jbyteArray jBuff = _env->NewByteArray(b->Length);       
    _env->SetByteArrayRegion(jBuff,b->Length,(jbyte*) buff);

    //call the java method
    jstring str = (jstring) _env->CallStaticObjectMethod (  Main,javaMethod,jBuff);



    // _env->ReleaseByteArrayElements(jBuff,(jbyte*)buff),0); //NOT WORKING

    //staticArray= _env->NewGlobalRef(jBuff);  NOT
    //_env->DeleteLocalRef(jBuff);             WORKING  


    //return the string result of the java method
    return gcnew String(env->GetStringUTFChars(str,0));

}
