Installing mysql-connector-java-8.0.15-1.el6.noarch.rpm (available here ) shows libgcj package as a dependency. Installing libgcj creates below file:

/usr/bin/gij

$/usr/bin/gij -version
java version "1.5.0"
gij (GNU libgcj) version 4.4.7 20120313 (Red Hat 4.4.7-23)

So, is the MySQL java connector still using Java 1.5 ?
