The Java exploit JAR files are downloaded from:

The JAR file exploits the vulnerability in the Java Runtime Environment component of Oracle Java SE (CVE-2012-0507), more details from the oracle.com website:

Vulnerability in the Java Runtime Environment component of Oracle Java SE (subcomponent: Concurrency). Supported versions that are affected are 7 Update 2 and before, 6 Update 30 and before and 5.0 Update 33 and before. Easily exploitable vulnerability allows successful unauthenticated network attacks via multiple protocols. Successful attack of this vulnerability can result in unauthorized update, insert or delete access to some Java Runtime Environment accessible data as well as read access to a subset of Java Runtime Environment accessible data and ability to cause a partial denial of service (partial DOS) of Java Runtime Environment.
