Gustavo Martin updated SUBMARINE-487:
-------------------------------------
Description:
In order to create an uber jar, Java packages must be renamed. Renaming
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]
The native library used by 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 renames packages, JNA fails when trying to call the
native method getNativeVersion (which is always called when using JNA for the
first time):
