CSS Import Resolver resolves the @import url(...); statements in input CSS files (by replacing the @import statement with the actual content of the linked CSS) and creates a huge CSS output (written to STDOUT by default). Including the combined CSS in your Web pages will improve the performance of a site by avoiding additional HTTP roundtrips.
kongcurrent provides an easy-to use helper to assist debugging issues which cause exceptions under concurrent access. It was inspired by a problem in which a non-thread-safe Map object held by a third party framework was accidentally shared between threads, causing a ConcurrentModificationException. The helper (a "monitor") creates a proxied version of an object implementing some interface. The proxy can track invocations of the objects' methods and can report on potential concurrent access on the object. This can be used to help find code paths which concurrently access the object through its interface methods. By design, the helper is extensible, and can be adapted to more specific needs.
