Examples of com.google.common.util.concurrent.UncheckedExecutionException

com.google.common.util.concurrent.UncheckedExecutionException
Unchecked variant of {@link java.util.concurrent.ExecutionException}. As with {@code ExecutionException}, the exception's {@linkplain #getCause() cause}comes from a failed task, possibly run in another thread.
{@code UncheckedExecutionException} is intended as an alternative to{@code ExecutionException} when the exception thrown by a task is anunchecked exception. This allows the client code to continue to distinguish between checked and unchecked exceptions, even when they come from other threads.
When wrapping an {@code Error} from another thread, prefer {@link ExecutionError}. @author fry@google.com (Charles Fry) @since Guava release 10
