How to suppress htmlunit (Java library) warning/error messages?

I'm using htmlunit [http://htmlunit.sourceforge.net/] and it spews out a bunch of warnings/error:
Mar 24, 2017 6:37:30 PM com.gargoylesoftware.htmlunit.IncorrectnessListenerImpl notify

I've looked at other resources and tried to turn it off by:
Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(Level.OFF);
Logger.getLogger("org.apache.http").setLevel(Level.OFF);
and:
final WebClient webClient = new WebClient(BrowserVersion.EDGE);
but it does not work.
What else can be done to suppress these warning/error messages?

If you are not going set the loggers to OFF in 'logging.properties' file then you need pin the loggers with a hard reference before you set the level to OFF.
Here is a corrected example based off your code:
private static final Logger[] PINNED_LOGGERS;
static {
System.setProperty("org.apache.commons.logging.simplelog.defaultlog", "fatal");
PINNED_LOGGERS = new Logger[]{
Logger.getLogger("com.gargoylesoftware.htmlunit"),
Logger.getLogger("org.apache.http")
};
for (Logger l : PINNED_LOGGERS) {
l.setLevel(Level.OFF);
}
}

I put the following at the start of the application and the errors/warnings stopped:
System.getProperties().put("org.apache.commons.logging.simplelog.defaultlog", "fatal");
Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(Level.OFF);
Logger.getLogger("org.apache.http").setLevel(Level.OFF);

Getting Error while creating EventHubClient in Microsoft Azure

I am using the latest 0.8.2 jar for java eventhub library and I have used the following code to send the data to azure eventhub :
ConnectionStringBuilder connStr = new ConnectionStringBuilder(connectionstring);
byte[] payloadBytes = valueChangeMessage.data.get().toString().getBytes("UTF-8");
EventData sendEvent = new EventData(payloadBytes);
EventHubClient ehClient = EventHubClient.createFromConnectionStringSync(connStr.toString());
ehClient.sendSync(sendEvent);
But I am getting the following error:

Can anyone help me with finding the possible issue for this?

Errors running HtmlUnit with Java

Attempting to use HtmlUnit. I want to input a username(pin) and password(password) and get to the next page. The output is a long list of errors.
I am unable to post all the errors. However, the majority are duplicates. I've posted below each unique error message I've received:

How to use HtmlUnit in Java?
Groovy htmlunit getFirstByXPath returning null + OCR Question
Here is the code:
public ApplicationLogin(String pin, String password) throws Exception {
WebClient webClient = new WebClient();
HtmlPage webPage = webClient.getPage("https://app.applyyourself.com/AYApplicantLogin/fl_ApplicantLogin.asp?id=dukegrad");
HtmlForm form = webPage.getFirstByXPath("//form[#id='frmApplicantLogin']");
HtmlTextInput username = form.getInputByName("UserID");
HtmlPasswordInput pass = form.getInputByName("Password");
HtmlSubmitInput b = form.getInputByValue("login");
username.setValueAttribute(pin);
pass.setValueAttribute(password);
HtmlPage webPage2 = b.click();
}

Use another WEB driver instead of default. For instance it could be CHROME (you can chose between different browsers like CHROME, FIREFOX_31, FIREFOX_31, INTERNET_EXPLORER_8, INTERNET_EXPLORER_11 ).
WebClient webClient = new WebClient(BrowserVersion.CHROME);
I suppose it should fix your problem.

Expected content type of 'application/javascript' in HtmlUnitDriver

i'm trying to execute javascript but couldn't find any way to do so ..
i have to mention that i've tried my code with FirefoxDriver and it's work great and do exactly what i want but the problem with FirefoxDriver is that the browser actually work and visible to user which i don't want . that's why i've switch to HtmlUnitdriver
--here's my code--
HtmlUnitDriver driver = new HtmlUnitDriver(true);
driver.get("https://blahblah.edu/home.faces");
WebElement select = driver.findElement(By.name("loginForm:userType"));
Select tbs = new Select(select);
tbs.selectByValue("1");
driver.findElement(By.name("loginForm:username")).sendKeys("username");
driver.findElement(By.name("loginForm:password")).sendKeys("password");
driver.executeScript("javascript:userTypeSelect();");//throws exception
driver.executeScript("if(typeof jsfcljs == 'function'){jsfcljs(document.getElementById('menuForm'),{'menuForm:serLinkDropAdd2':'menuForm:serLinkDropAdd2'},'');}return false");
WebDriverWait driverWait = new WebDriverWait(driver, 10000);
driverWait.until(ExpectedConditions.presenceOfElementLocated(By.id("saveBut1")));
driver.findElement(By.id("saveBut1")).click();
System.out.println(driver.getTitle());
--here's the Error--

Login Using HtmlUnit

I am very very new to HtmlUnit. I want to know do I am able to login to a site using htmlunit and perform some operations in the site for example I want to login to my office portal and to aplly a leave.I am using html unit and it shows some errors, is its possible to do with html unit or are there any other tools I can use for this purpose... Here is my code
final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_3_6);
webClient.setJavaScriptEnabled(true);
webClient.getCookieManager().setCookiesEnabled(true);
final HtmlPage page1 = webClient.getPage("http://www.ccstechnologies.org/login.aspx/");
final HtmlForm form = page1.getFormByName("form1");
final HtmlSubmitInput button = form.getInputByName("BtnLogin");
final HtmlTextInput textField = form.getInputByName("Username");
final HtmlPasswordInput pwd = form.getInputByName("password");
textField.setValueAttribute("username");
pwd.setValueAttribute("password");
final HtmlPage page2 = button.getEnclosingForm().click();
String htmlBody = page2.getWebResponse().getContentAsString();
System.out.println("Base Uri 1 : "+page1);
System.out.println("Base Uri 2 : "+page2);
webClient.closeAllWindows();
But when I print page2 it shows only the login page's url, and it is not returning the homepage url. What could be the problem ?
This is what I got in my console when clicked on form

Ok, I looked into it, it would seem the problem was with the button. I replaced you line of code for the button with this:
final HtmlPage page2 = (HtmlPage) form.getInputByValue("Login").click();
now it appears that it at least tries to login(and the page of course prints invalid login) so it should work with appropriate credentials.
to print the page in java and see it use system.out.println(page1.asText()) or asXml depending on what you want to see
my code is finally this:
final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_3_6);
webClient.setJavaScriptEnabled(true);
webClient.getCookieManager().setCookiesEnabled(true);
try{ final HtmlPage page1 = webClient.getPage("http://www.ccstechnologies.org/login.aspx/");
final HtmlForm form = page1.getFormByName("form1");
final HtmlSubmitInput button = form.getInputByName("BtnLogin");
final HtmlTextInput textField = form.getInputByName("Username");
final HtmlPasswordInput pwd = form.getInputByName("password");
textField.setValueAttribute("username");
pwd.setValueAttribute("password");
System.out.println(page1.asText());
final HtmlPage page2 = (HtmlPage) form.getInputByValue("Login").click();
String htmlBody = page2.getWebResponse().getContentAsString();
System.out.println(page2.asText());
System.out.println("Base Uri 1 : "+page1);
System.out.println("Base Uri 2 : "+page2);
webClient.closeAllWindows();}catch (Exception e) {
// TODO: handle exception
}

this is what you should set for the javascript:
webClient.getOptions().setJavaScriptEnabled(false);
and you can as well add these to it.
webClient.getOptions().setRedirectEnabled(true);
webClient.getOptions().setThrowExceptionOnScriptError(false);
webClient.getOptions().setCssEnabled(false);
webClient.getOptions().setUseInsecureSSL(true);
webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
webClient.getCookieManager().setCookiesEnabled(true);
This should solve the problem as it did for me.

try to set cookies enabled, and try to set javascript enabled
ignore errors that it might print...(I used to think errors in red are bad, in html unit it seems not necessarily)

If the website uses an ajax call to login.
This worked for me. Set this
webClient.setAjaxController(new NicelyResynchronizingAjaxController());
This would cause all ajax calls to be synchronous.
This is how I setup my WebClient object
WebClient webClient = new WebClient(BrowserVersion.CHROME);
webClient.getOptions().setJavaScriptEnabled(true);
webClient.getOptions().setCssEnabled(false);
webClient.getOptions().setUseInsecureSSL(true);
webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
webClient.getCookieManager().setCookiesEnabled(true);
webClient.setAjaxController(new NicelyResynchronizingAjaxController());
webClient.getOptions().setThrowExceptionOnScriptError(false);
webClient.getCookieManager().setCookiesEnabled(true);
