Guava is a suite of core and expanded libraries that include utility classes, google's collections, io classes, and much much more. This project is a complete packaging of all the Guava libraries into a single jar. Individual portions of Guava can be used by downloading the appropriate module and its dependencies. Guava (complete) has only one code dependency - javax.annotation, per the JSR-305 spec.

There is a newer version: 33.2.0-jre

/**
 * A TimeLimiter implementation which actually does not attempt to limit time
 * at all.  This may be desirable to use in some unit tests.  More importantly,
 * attempting to debug a call which is time-limited would be extremely annoying,
 * so this gives you a time-limiter you can easily swap in for your real
 * time-limiter while you're debugging.
