native-utils | simple library class which helps with loading dynamic JNI | Wrapper library

I develop an app in java that loads a C++ shared library using JNA. The detailed procedure is the following.

1. Find library in the jar
2. use System.load( C_LIBRARY_PATH ) with the result of step 1
3. Load library using JNA tools: Wrapper INSTANCE = Native.loadLibrary( C_LIBRARY_PATH, Wrapper.class );

This procedure is used to create a wrapper of the c++ library and hence produces a java library that is used for other projects. Point 1 and 2 are inspired by the work of adamheinrich. The existence of the file is checked before calling the load function.

When using the java wrapper in a project I randomly have an error like below. Could you guide me in debugging and try to control this random failure?

I use JNA to load a c++ library (.so) in a java project. I package my library inside the jar, and load it from the jar when instantiating the java class that uses it. I do all this like so:

• mvn install compiles the c++ code and packages the outcome dynamic library inside the jar.

• I call in a static context when instantiating the LibraryWrapperClass the following
