Hybris Server showing Garbage collection issue?

I had recently installed java adopt JDK 1.8.0_202 version.
It worked fine for the first time and later when i start hybris server getting the below issue again & again on console :

This logs produced by -verbose:gc (or similar) JVM option.
You should remove that option if you don't need this logs.

how to make a form field of type List<Inventory> for camunda rest api

We're going to build a workflow management system and We're embedding the camunda engine Rest API into our Rest Application.
Now I have Inventory defined like this:
public class Inventory {
private String objectName;
private int objectCount;
// getters and setters
}
and this is a sample workflow:

I'll eventually have a html form which will submit something like this:
{
"inventories" : [{"name": "banana","count": 3},{"name":"orange","count": 4}]
}
I want to submit this to /task/{id}/submit-form but I don't know what to put as type.
I tried putting the type in modeler as List<org.example.Inventory> but the rest api throws an exception when deploying the process definition like this:
org.camunda.bpm.engine.ProcessEngineException: ENGINE-09005 Could not parse BPMN process. Errors:
* unknown type 'List' | org.example/PM.bpmn | line 65 | column 90
I've seen this example as well but I'm only using the Rest API not the whole bpm platform(besides we prefer to have pure html forms).
So how to do it ? what should I put in type ?

I know the error is occurring because of this line: System.out.println("caffeineIntake");
I want to access this input variable i.e. caffeineIntake to perform some operation on it.

The error is not occurring because of this line: System.out.println("caffeineIntake");
It is occurring because of the Dialect option selection:
Using this option as mvel rather than java resolved the issue.

Well,
from my point of view
String noOfCups = 1;
is the problem.
perhaps change it to
String noOfCups = "1";

Spring security with oauth2 adding additional parameters to authorization URL?

I have implemented Spring Security in my restful web service. In fact, I have to add an extra parameter with the request from client side and should fetch it from the service when request for authentication/accesstoken.

Currently I am requesting with the URL:
http://localhost:8084/Domain/oauth/token?grant_type=password&client_id=restapp&client_secret=restapp&username=anoo#codelynks.com&password=mypass
And I will get the response
{
"access_token":"76e928b2-45e2-4283-88a4-6c01f41b51d3","token_type":"bearer","refresh_token":"8748e8ad-79c1-465d-94fe-13394eea370d","expires_in":119
}
I have to enhance it by adding additional parameter deviceToken.
And the URL would be:
http://localhost:8084/Domain/oauth/token?grant_type=password&client_id=restapp&client_secret=restapp&username=anoo#codelynks.com&password=mypass&deviceToken=something
I have treid by implementing UsernamePasswordAuthenticationFilter, but it didn't work. How can I get the deviceToken parameter from the web service without affecting the output?

http://localhost:8084/Domain/oauth/token?grant_type=password&client_id=restapp&client_secret=restapp&username=anoo#codelynks.com&password=mypass&additional_param=abc123
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
log.info("additional_param: " + request.getParameter("additional_param"));
log will show
additional_param: abc123

Although AOP is used when it comes to crosscutting concerns, this approach worked as expected and I think It is a valid approach.
#Aspect
public class Oauth2Aspect {
#AfterReturning("execution( * org.springframework.security.oauth2.provider.endpoint.TokenEndpoint.postAccessToken(..))")
public void executeAfterAuthentication() throws Exception {
System.out.println(":Authentication done");
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
System.out.println(":Authentication done " + request.getParameter("deviceInfo"));
}
}
