> In order to create a uber jar, Java JNA packages are being renamed. Renaming JNA packages makes JNI fail.
>
> 1. ranger-plugins-common requires JNA through com.kstruct:gethostname4j
> See the following code: [https://github.com/apache/ranger/blob/release-ranger-2.0.0/agents-common/src/main/java/org/apache/ranger/plugin/util/RangerRESTUtils.java#L83]
> 2. gethostname4j uses JNA, through net.java.dev.jna:jna
> See the followingcode: [https://github.com/mattsheppard/gethostname4j/blob/master/src/main/java/com/kstruct/gethostname4j/Hostname.java#L30]
> 3. net.java.dev.jna:jna uses JNI
> See the following code: [https://github.com/java-native-access/jna/blob/master/src/com/sun/jna/Native.java#L1018]
> 4. The native library used by net.java.dev.jna:jna is libjnidispatch.so.
> libjnidispatch.so was compiled with the package com.sun.jna (example for linux-x86-64):
> {noformat}
> readelf -aW libjnidispatch.so | grep Java_com_sun_jna_Native_getNativeVersion
> 178: 000000000000bde0 24 FUNC GLOBAL DEFAULT 12 Java_com_sun_jna_Native_getNativeVersion
> 227: 000000000000bde0 24 FUNC GLOBAL DEFAULT 12 Java_com_sun_jna_Native_getNativeVersion
> {noformat}
>
> Because maven-shade-plugin is renaming JNA packages, JNA fails when trying to call the native method getNativeVersion (which is always called when using JNA for the first time):
