---------------------------------------------------------

             Summary: Creating a service based on a sealed interface causes exception
                 Key: TAP5-2709
                 URL: https://issues.apache.org/jira/browse/TAP5-2709
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-ioc
    Affects Versions: 5.7.3, 5.7.2, 5.7.1, 5.7.0
            Reporter: Thiago Henrique De Paula Figueiredo


If you have a sealed interface, like this example:

{code:java}
public sealed interface IntExpression permits ConstantIntExpression, PlusExpression, SquareExpression {
    ...
}
{code}

and define a service based on it, like this example:

{code:java}
        @Marker(Primary.class)
        public static IntExpression buildIntExpression() {
            return (...);
        }
{code}

This exception is thrown, since Tapestry-IoC is trying to create a proxy for it by creating a non-permitted implementation of the sealed interface:
