### Question:
NodeBuilderBaseImpl { public B withoutErrorHandler() { errorHandler.set(null); return ensureRuntimeSelfReference(); } NodeBuilderBaseImpl();   NodeBuilderBaseImpl(final Node node); B withErrorHandler(final ErrorHandler errorHandler); B withoutErrorHandler(); B withName(final String name); B withCredential(final Credential credential); B withoutCredential(final Credential credential); B clearCredentials(); B withRetryMax(final Integer retryMax); B withRetryInterval(final Integer retryInterval); B withRetryPolicy(final String retryPolicy); B withParent(final Node parent); B withParentWithCondition(final Node parent, final String condition); B withParentDefaultConditional(final Node parent); B withoutParent(final Node parent); B clearParents();  }### Answer:
@Test public void testWithoutErrorHandler() { final ErrorHandler errorHandler = ErrorHandler.buildAsErrorHandler( MapReduceActionBuilder.create().withName("error-handler")); final B builder = getBuilderInstance(); builder.withErrorHandler(errorHandler); final N node = builder.build(); final B fromExistingBuilder = getBuilderInstance(node); fromExistingBuilder.withoutErrorHandler(); final N modifiedNode = fromExistingBuilder.build(); assertEquals(null, modifiedNode.getErrorHandler()); }
