Steps to reproduce:

1. Update sample-service-builder-portlet to match Liferay version being tested. In master, this means replacing the call to GroupServiceUtil.getUserPlacesGroups() to getUserSitesGroups() and removing the version requirement in liferay-plugin-package.properties
2. Create a new portlet sample-service-user-portlet which has sample-service-builder-portlet as a required deployment context and calls FooLocalServiceUtil.addFoo() with a foo where field1 is larger than 75 characters.
3. Deploy sample-service-user-portlet and sample-service-builder-portlet

Expectation is that you get a SystemException due to the column constraint restriction, and the stack trace indicates that it is caused by the data being too long. Actual behavior is that you get a RuntimeException caused by a ClassNotFoundException with no additional information.
