There currently seems to be a JIRA service desk bug affecting workflow validators. Note that using the following will not work:

import com.opensymphony.workflow.InvalidInputException
 
throw new InvalidInputException("In Progress", "This won't work")

Resulting in a error message being shown and an exception in the logs:

17-Mar-2016 02:18:26.669 WARNING [http-nio-8080-exec-5] com.sun.jersey.spi.container.servlet.WebComponent.filterFormParameters A servlet request, to the URI https://jira-dev.cloud.twc.net/rest/servicedesk/1/customer/pages/portal/35/create/176, contains form parameters in the request body but the request body has been consumed by the servlet or a servlet filter accessing the request parameters. Only resource methods using @FormParam will work as expected. Resource methods consuming the request body by other means will not work as expected.

But interestingly as a workaround this will work:

import com.opensymphony.workflow.InvalidInputException
 
throw new InvalidInputException("This will work")

It's a bug in JSD, it fails to show validation errors. Maybe: https://jira.atlassian.com/browse/JSD-1638
