Kiwi is a utility library. We really like Google's Guava, and also use Apache Commons. But if they don't have something we need, and we think it is useful, this is where we put it.
There is a newer version: 4.5.2

/**
 * Some JAX-WS utilities and constants. These make use of specific features in the JDK/Apache CXF implementation
 * in order to provide connect and read timeouts, as well as to provide an {@link SSLSocketFactory}. See
 * the implementation note for more details if you are not using the JDK/Apache CXF implementations.
 *
 * @implNote Note specifically that these use JAX-WS reference implementation vendor extension features that are
 * available only when using the JAX-WS reference implementation. Specifically we are using constants in
 * {@link JAXWSProperties}. If you are not using the reference implementation, this will almost certainly not
 * work. For one thing you won't have JAXWSProperties in your classpath, so will most likely get
 * {@link NoClassDefFoundError} or {@link ClassNotFoundException} at runtime.
