As it can be understood from OpenJDK, I'm using Java 1.7. 

Also I've obtained a timeout error as below just after the error above:

# A fatal error has been detected by the Java Runtime Environment:
#

I can't offer my support for JDK. This is a domain I'm not expert in.

If you are willing to use LZ4 in a Java program, I can only offer you to 
consider Adrien Grand's version, at https://github.com/jpountz/lz4-java

After all, his version is already validated in large production environments, 
and should be safe of obvious (and less obvious) problems.

seems unrelated to LZ4 C version
