System.loadLibrary适用于OpenJDK，但不适用于Oracle

Question

I implemented a SDK in C++ (API exported in C). This SDK compiles into a DLL for Windows and a .so for Linux. I also implemented a Java wrapper using JNA. This wrapper ships with .so and DLL inside it and I check at runtime which operation system is running and extract it on a folder specified by developer. It works well.

The problem is that one of customers that use Linux (I have just a couple of them on Linux) said that the library was not loading with a undefined symbol error. Here is the error:

java.lang.UnsatisfiedLinkError: /usr/lib/libBXSDK.so: /usr/lib/libBXSDK.so: undefined symbol: _ZTVN10__cxxabiv117__class_type_infoE

Initially I thought this could be related to some standard .so not being present. I then sent him aa very basic C++ executable and asked him to run. It worked. I then sent him a very basic Java application that DOES NOT use the SDK, but only calls System.loadLibrary("BXSDK"). After copying libBXSDK.so to /usr/lib, he ran the basic Java application and the error was the same.

I then decided to check his Java version, and realized he was using Oracle JDK latest version, and I saw that on my test environment that runs CentOS 7 (customer runs RHEL 7) I use OpenJDK. Immediately I installed Oracle JDK on my test environment and I saw the same problem.

So, my question is. What is the difference between Oracle JRE and OpenJDK (JRE), that causes this issue? Am I doing something wrong on my .so that OpenJDK is able to handle but Oracle JRE is not?

Thanks

Did you verify if the folder is the case as mentioned in this post: http://ubuntuforums.org/showthread.php?t=1323888

Fellow (dontexist) member's comment is quite valid in general, the fact that OpenJDK being able to make the calls makes me think if library load itself was unsuccessful.

I figured, this may not entail an answer to the question - "What is the difference between Oracle and Open JDK in loading semantics". Not sure if I can retract this post being an answer, but let others take the opportunity to explain about it.
