I have a class named GameHelpers. This class should contain useful methods for the game. The game happenes

You may refer Java to EXE - Why, When, When Not and How

Drawbacks

Disk footprint. Java bytecode has been designed for compactness, so it has a much higher level than a typical CPU instruction set. Expect that an executable produced by an AOT compiler will be 2-4 times larger than the original jar file.

Dynamic applications. Classes that the application loads dynamically at runtime may be unavailable to the application developer. These can be third-party plug-ins, dynamic proxies and other classes generated at runtime and so on. So the runtime system has to include a Java bytecode interpreter and/or a JIT compiler.

Moreover, in the general case only classes that are loaded by either system or application classloader may be precompiled to native code. So applications that use custom classloaders extensively may only be partially precompiled.

Hardware-specific optimizations. A JIT compiler has a potential advantage over AOT compilers in that it can select code generation patterns according to the actual hardware on which the application is executing. For instance, it may use Intel MMX/SSE/SSE2 extensions to speedup floating point calculations. An AOT compiler must either produce code for the lowest common denominator or apply versioning to the most CPU-intensive methods, which results in further code size increase.

Speaking from personal experience, if there's a bug that's only present in the EXE version, you might end up spending a lot of time trying to track it down and decide it's just easier to give users the other version instead.

It sounds to me like you're really trying to make things easier on your users overall. I don't know what your budget is, but perhaps something like install4j would be a better solution.
