unsupported JNI version 0xFFFFFFFF

has anyone encountered that error while using native dll from java code? Is it the version of the JNI library? or an unresolved dependency?

The error:

Caused by: java.lang.UnsatisfiedLinkError: unsupported JNI version 0xFFFFFFFF required by C:\jnwasapi.dll
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary1(Unknown Source)
at java.lang.ClassLoader.loadLibrary0(Unknown Source)
at java.lang.ClassLoader.loadLibrary(Unknown Source)
at java.lang.Runtime.loadLibrary0(Unknown Source)
at java.lang.System.loadLibrary(Unknown Source)

This is a new library I'm using, the others working fine.

The jnwasapi.dll's JNI_OnLoad function is probably returning -1, which is not an expected value. The JNI_OnLoad function must return a jint with a known constant, such as JNI_VERSION_1_6. It's common for JNI_OnLoad functions to return -1 if they fail to initialize. For example, it may have tried to load a class which couldn't be found.
