How to fix the issue.

1. Go to https://github.com/xerial/snappy-java and clone the git to your mac.
2. Once cloned, check the directory. If there are any files inside "target" folder, delete them. Else continue to next step.
3. Open the terminal to the cloned directory and run the "make" command. It might take some time to build.
4. Once the build is completed, go to the following folder - "target/snappy-1.1.1-Mac-x86_64".
5. There you will see a file with name "libsnappyjava.jnilib".
6. Copy this file to WSO2 MB home directory.
7. Now run "./wso2server.sh" in the bin folder.


Hope that fixed your issue !.
