Nothing new has been displayed. > Try using JDK 7 to do compile for 1.7 target, instead of using JDK 8. I did exactly this in (4) and now retested again. It is really weird. While in MANIFEST can be found 'created by' JDK 7, when that main class is executed in JDK 7, it fails (unsupported major.minor 52). Manifest-Version: 1.0 Ant-Version: Apache Ant 1.9.6 Created-By: 1.7.0_80-b15 (Oracle Corporation) Implementation-Title: Batik SVG rasterizer Implementation-Version: svn-trunk Implementation-Vendor: The Apache Software Foundation (http://xmlgraph ics.apache.org/batik/) Main-Class: org.apache.batik.apps.rasterizer.Main Build-Id: 20161220-223305-CET (Honza [Windows 8.1 6.3 amd64, Java 1.7. 0_80-b15]) I suspect this is Ant/compiler issue of incorectly written version stamp into class files. I'll ask Ant developers.
