JNA (Java Native Access) is a Java library that allows Java code to call and be called by native applications and libraries written in other languages, such as C and C++. An "invalid memory access" error occurs when the JNA library tries to read or write to a memory location that is not valid or accessible.
This error can occur for various reasons, such as:
1. A null pointer was passed to a JNA function that expects a valid pointer.
2. The size of the buffer passed to a JNA function is incorrect or too small.
3. The native library being called has an error in its implementation that causes a memory access violation.
To fix this error, you need to carefully review your JNA code and make sure that all pointers and buffers are properly initialized and sized. You may also need to debug the native library being called to identify and fix any memory access violations in its implementation. Additionally, you can try running your application with debugging tools like Valgrind or GDB to help pinpoint the root cause of the error.
