Description
This module takes advantage of the default configuration of the RMI Registry and
RMI Activation services, which allow loading classes from any remote (HTTP) URL. As it
invokes a method in the RMI Distributed Garbage Collector which is available via every
RMI endpoint, it can be used against both rmiregistry and rmid, and against most other
(custom) RMI endpoints as well.
Note that it does not work against Java Management Extension (JMX) ports since those do
not support remote class loading, unless another RMI endpoint is active in the same
Java process.
RMI method calls do not support or require any sort of authentication.
