"Could not allocate library name" when load native library by JNA.

I tried to load my c library using the following code.

Native.register(com.sun.jna.NativeLibrary.getInstance("c", Collections.emptyMap()));

When Phosphor applied, a fatal error occurs. Here’s the information:

My JNA version is 4.2.2. The pom info is as follows

<dependency>
    <groupId>net.java.dev.jna</groupId>
    <artifactId>jna</artifactId>
    <version>4.2.2</version>
</dependency>

Could you help figure out what happens?
