You're correct that git client plugin 1.19.6 includes a jar file that is compiled with JDK 7. The JGit support for symlinks requires it. However, that jar file should not be loaded if it is running on a Java 6 environment. The JGit implementation is designed to allow the Java 7 module to only be loaded if it detects it is running on JDK 7 or newer.
I definitely do not see class version errors in a JDK 1.6 environment. I configured a Docker instance yesterday with Java 6 master, Java 7 slaves, and confirmed that I could clone to both the master and the slaves using Git plugin 2.4.4 and Git client plugin 1.19.6.
