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:

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);

How to call a POST method using gluon RESTClient

Below is the sample code . i want to call a rest api using gluon.
RestClient restClient = RestClient.create()
.host("https://abc.api.in")
.path("v1/signup")
.formParam("name",name)
.formParam("email",email)
.formParam("password",password)
.formParam("repeatPassword",repeatPassword)
.formParam("refID",refID)
.method("POST").contentType("text/plain");
GluonObservableObject<SignUpDAO> sample = DataProvider.retrieveObject(restClient.createObjectDataReader(SignUpDAO.class));
But it gives warning like and it is not showing any further progress.I am using Task to call rest client from my controller.

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.

SEVERE: Job run failed with unexpected RuntimeException: Exception invoking setInnerHTML

Those are not errors, they are warnings.
They are caused by HtmlUnit's JavaScript engine Mozilla’s Rhino being unable to properly interpret some JavaScript code. (It is not as "good" as some other popular JS Engines.)
You can turn those warnings off, here's how:
public static void main(String[] args) throws Exception {
// turn off htmlunit warnings
java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(java.util.logging.Level.OFF);
java.util.logging.Logger.getLogger("org.apache.http").setLevel(java.util.logging.Level.OFF);
WebClient webClient = new WebClient();
HtmlPage page = webClient.getPage("http://stackoverflow.com");
System.out.println(page.getTitleText());
}
Output:
Stack Overflow

Set enable Javascript and CSS in the webClient browser as:
webClient.getOptions().setJavaScriptEnabled(false);
webClient.getOptions().setCssEnabled(false);
You can ON / OFF by passint true or false parameters.
