Hi, About "incompatible-java-bytecode-format with OpenJDK 7 as default-jdk" issue, I wonder which version should be specified to keep backward compatibility. https://bugs.launchpad.net/ubuntu/+bugs?field.tag=java7-bytecode
I've found this is reported in LP#1049779. And I've investigated how should be fixed, and specifying target version is good way. But I cannot decide which version would be used. In Bug#673177, it is specified with 1.4. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=673177 > * Build class files with source/target = 1.4 to ensure backwards > compatibility. Thanks to James Page. (Closes: #673177) And Bug#679365, it is 1.5. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=679365 > diff -Nru pylucene-3.5.0/debian/ant.properties > pylucene-3.5.0/debian/ant.properties > --- pylucene-3.5.0/debian/ant.properties 1970-01-01 01:00:00.000000000 > +0100 > +++ pylucene-3.5.0/debian/ant.properties 2012-06-28 10:15:05.000000000 > +0200 > @@ -0,0 +1,4 @@ > +# Ensure that source and target are 1.5 > +# For backwards compat on Java 7 > +ant.build.javac.source=1.5 > +ant.build.javac.target=1.5 However, James said "Default base target version should be Java6" in discussion for lintian. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=673276 So, 1.4, 1.5 or 1.6? > This is somewhat complicated by the fact that on kfreebsd we still don't have > openjdk, so we're using GCJ/GIJ, which is really a 1.5 implementation. If it's true, 1.5. If not, 1.6 IMO. -- Regards, Hideki Yamane henrich @ debian.or.jp/org http://wiki.debian.org/HidekiYamane __ This is the maintainer address of Debian's Java team <http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-java-maintainers>.
