J2V8 4.6 On Linux

Using J2V8 in an existing project and adding it using the following Maven dependency -

com.eclipsesource.j2v8
j2v8_linux_x86_64
4.6.0

But, NodeJS.createNodeJS(); fails with the following error message - "J2V8 native library not loaded"

But the same code works when I deploy the project on Windows with the following Maven dependency -

com.eclipsesource.j2v8
j2v8_win32_x86_64
4.6.0

Looks like the .so file is not found on Linux.

Why this discrepancy with the same code on two platforms?

And what is the work around for this?
