    // thrown.expectCause(isA(IllegalStateException.class));
    ResultCollector rc = getExecution().execute((context) -> {
        context.getResultSender().sendResult(new IllegalStateException());
        context.getResultSender().lastResult("done");
    });
    final Object result = rc.getResult();
}

}

Example 45 with ResultCollector

use of org.apache.geode.cache.execute.ResultCollector in project geode by apache.

the class FunctionServiceBase method defaultCollectorThrowsExceptionAfterFunctionReturnsIllegalStateException.

/**
   * Tests what happens if a function returns an exception as a result. This is kind a weird, but it
   * seems that the default collector will just throw it as an exception
   */
