Package tomcat appears to be using Java generics, but generates class files in format older than 49.0, which corresponds to J2SE 5.0, in which generics were introduced. Please update this package to generate classes in format 49.0 or above. This corresponds to -target 1.5 option of javac (or ecj). For more information, see bug #842394
It seems tomcat package already build in 50 format. also build.xml: <!-- Servlet 3.0 spec requires 1.6+ --> <property name="compile.source" value="1.6"/> <property name="compile.target" value="1.6"/>
These 2 jars have classes in format 48.0: /var/lib/tomcat/webapps/examples/WEB-INF/lib/jstl.jar /var/lib/tomcat/webapps/examples/WEB-INF/lib/standard.jar These are part of tomcat-webapps binary RPM build from tomcat SRPM To see the full list of affected classes, you can try: curl http://mizdebsk.fedorapeople.org/jsr14-rawhide-2012-07-23.gz | zgrep ^tomcat-webapps- You can also use javap to check class versions.
