The first warning ‘includeantruntime’ is something that should have seen in 8.5 also. It is a “misfeature” of ant 1.8 that we use when calling the java compiler.
The second warning comes from our “target=1.6” setting in the XML for the application being compiled. We set this to 1.6 in order to allow backward compatibility. Some app servers are still using 1.6 runtimes and we did this to allow Gen users to still target those app servers. Since are not yet using newer, post 1.6, java features, the users will not experience runtime problems.
Both warning messages can be safely ignored.
