Summary: Groovy sandbox for executing untrusted Groovy scripts safely

Description:
This project defines a Groovy CompilationCustomizer, which allows a
program to execute Groovy script in a restricted sandbox environment. It
is useful for applications that want to provide some degree of
scriptability to users, without allowing them to execute System.exit(0)
or any other undesirable operations.

This compile-time transformation modifies untrusted Groovy script in
such a way that every operation that can cause interactions with the
external world gets intercepted. This allows your code to examine and
deny executions. This includes every method call, object allocations,
property/attribute access, array access, and so on.
