This is not java 8 specific. The method lookup is done using return type too - check bytecode with javap for instance. I didnt check if a cast fixes it but using a temp var should or moving the impl typing to the interface at field level fixes it in tomcat and no api is missing AFAIK. > -chris > > --------------------------------------------------------------------- > To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org > For additional commands, e-mail: dev-h...@tomcat.apache.org >
