Hello everyone. The setup I have is I'm using a
Java application to call native C-code with JNI, which in turn starts up the MATLAB runtime and calls functions on it (I know there are other solutions to call MATLAB methods from Java).
The problem is that the MATLAB engine crashes at some point during the initialization and I don't know what's causing it exactly. The crash causes my jvm to terminate, I assume it's some kind of memory corruption.
The C++ code calling MATLAB functions that is actually crashing is
JNIEXPORT void JNICALL
some_jni_vodoo_initializeLibrary(JNIEnv* env, jclass thisClass) {
try {
if (!mclInitializeApplication(NULL, 0)) {
THROW_EXCEPTION(env, "Could not initialize the application properly.");
return;
}
if (!<library>Initialize()) {
THROW_EXCEPTION(env, "Could not initialize the library.");
return;
}
} ...
The function <library>Initialize() crashes here, the
Java error log reads

I really have no idea what could be wrong. Is there not enough memory from the jvm? I guess the problem is somehow related to
Java, since calling the JNI functions from a simple test C++ program works fine...
Thanks
