 *  Fix: Cancel calls that fail due to unexpected exceptions. We had a bug where an enqueued call
    would never call back if it crashed with an unchecked throwable, such as a
    `NullPointerException` or `OutOfMemoryError`. We now call `Callback.onFailure()` with an
    `IOException` that reports the call as canceled. The triggering exception is still delivered to
    the thread's `UncaughtExceptionHandler`.

corresponding java.util.logging.Logger instance. LogKit from Apache's Avalon project. Each named Log instance is connected to a corresponding LogKit Logger. NoOpLog implementation that simply swallows all log output, for all named Log isntances. SimpleLog implementation that writes all log output, for all named Log instances, to System.err. Quick Start Guide For those impatient to just get on with it, the following example illustrates the typical declaration and use of a logger that is named (by convention)...
