how to create a 'contains' syntax for principalExpression in domain security file

Issue Description

In a domain security file's principalExpression element, the typical example checks to see if a user's role is in a list of the roles provided, like:

authentication.getPrincipal().getRoles().any{ it.getRoleName() in ['ROLE_T_1, ROLE_T_2, ROLE_T_3, ROLE_T_99999'] ...

See https://community.jaspersoft.com/documentation/tibco-jasperreports-server-security-guide/v7/domain-and-security-recommendations for reference

But some users might want to check to see if any of a user's roles simply contain ROLE_T, for simplicity.  

Resolution

It is possible to use this expression in your principalExpression element:

authentication.getPrincipal().getRoles().contains('ROLE_T')

If any of the users's roles contain ROLE_T as part of the rolename, the expression will return true.
