![]() T H R E A D -Ĭurrent thread (0x082b4918): JavaThread "main" # Java VM: Java HotSpot(TM) Client VM (1.4.2_12-b03 mixed mode) # An unexpected error has been detected by HotSpot Virtual Machine: I've attached the HotSpot error log below. Nedit segmentation fault code#JNI_CreateJavaVM(jvm_ptr, (void**)jniEnv_p, (void*)&args) Is it possible that the seg fault is actually occuring in both cases on the CreateJavaVM line, but only gdb picks it up, having inserted itself between the VM creation code and the system calls which are seg faulting? Or is there something more bizarre going on here? Any general advice at all about using the invocation API in terms of compilation, code layout, VM creation etc. JniEnv->CallStaticVoidMethod(lib, methodId) However, when I run c_engine.exe through gdb the segfault (see below) occurs much earlier than this, right back when I'm creating the jvm: JmethodID methodId = jniEnv->GetStaticMethodID(lib, "myMethod", "()V") but falls over when we try to call the method: Jclass lib = jniEnv->findClass("lib") and when finding methods: Note, the second case still works in trying to find the library: The behaviour gets even more confusing when I try to debug this. Options = "-cp " and the layout changes to the one above, I get a seg fault when I attempt to call any method in lib.class. Jint result = JNI_CreateJavaVM(jvm_p, (void**)jniEnv_p, (void*)&args) Everything works fine, but as soon as I have the following directory structure, compiling and distributing everything with a simple make file:Ĭurrently in my code, if both lib.class and c_engine.exe are placed in src and I set the JVM options like this: The problems begin to occur when I want to separate out my executable and my java classes in the file system. I have followed the tutorial here up to the point where - provided I put my executable and my class files in the same directory I can happily create a JVM, find classes and method IDs and invoke methods on the java library. We are running Scientific Linux 2.4.21-47.0.1.ELsmp and using the j2sdk 1.4.2_12 with i386 client libjvm.so. We are looking to use the invocation API to host Java applications in a C++ app engine we've created. 1.7K Training / Learning / Certification.165.3K Java EE (Java Enterprise Edition).7.8K Oracle Database Express Edition (XE).3.7K Java and JavaScript in the Database.However you might be able to duplicate the error with just the vector allocation. ![]() On a 3570k 4.2GHz running 100 billion in visual studio takes around 30 mins, 1 billion around 10 seconds.
