Niclas Hedhman commented on POLYGENE-306:
-----------------------------------------

A complete example of what I would like to be able to do;

 
{code:java}
public class DynamicAnnotationTest extends AbstractPolygeneTest
{
    @Override
    public void assemble( ModuleAssembly module )
        throws AssemblyException
    {
        module.services( Map.class ).withMixins( HashMap.class );
        module.forMixin( HashMap.class )
              .annotations( annotation( Disabled.class ) )
              .put( null, null );
    }

    @Test
    void test1()
        throws Exception
    {
        Map underTest = serviceFinder.findService( Map.class ).get();
        assertThrows( DisabledMethodException.class, () -> underTest.put( "1", "2" ) );
    }

    @Target( ElementType.METHOD )
    @Retention( RetentionPolicy.RUNTIME )
    public @interface Disabled
    {
    }

    @AppliesTo( Disabled.class )
    public static class DisabledMethodConcern extends ConcernOf<InvocationHandler>
        implements InvocationHandler
    {

        @Override
        public Object invoke( Object o, Method method, Object[] objects )
            throws Throwable
        {
            throw new DisabledMethodException();
        }
    }

    public static class DisabledMethodException extends RuntimeException
    {
    }
}
{code}

>            Priority: Major
>
> Currently we can manipulate types pretty much freely at bootstrap, but we can't add annotations to methods, which would be useful for instance when working with external types not under one's control.
> This will need to add metaInfo to Property and add the annotation there, rather than trying to compile it into the method itself.
