I would ask such question on the Freemarker Users group, officially Freemarker 2.3.28 can run on Java 5 https://freemarker.apache.org/freemarkerdownload.html but looks like they support Java 8 with this class, disabling class scanning in your app should help (no idea what ScannerContextImpl is for). https://github.com/apache/freemarker/blob/2.3-gae/src/main/java/freemarker/core/_Java8Impl.java#L27 Regards -- Łukasz + 48 606 323 122 http://www.lenart.org.pl/ --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
