Because your stack traces have files and line numbers, I'm going to assume you're running with IcedTea. What arch is this? I'm running i386 with the exact same versions of the packages and I can't reproduce. $ java -version java version "1.7.0" IcedTea Runtime Environment (build 1.7.0-b21) IcedTea Client VM (build 1.7.0-b21, mixed mode) $ rpm -q java-1.7.0-icedtea java-1.7.0-icedtea-1.7.0.0-0.19.b21.snapshot.fc8 $ uname -m i686 Please post the output of: rpm -qV jetty for f in `rpm -qa | egrep "eclipse|swt"`; do rpm -qV $f; done Moving away my ~/.eclipse directory (which seems to have some old cached stuff in it) worked around it. Output requested: $ rpm -qV jetty $ for f in `rpm -qa | egrep "eclipse|swt"`; do rpm -qV $f; done S.5....T /usr/bin/ecj Mark's emailed me his .eclipse directories (the old one and the new one) so that I can examine when I have time. Closing as upstream since it's arguably an upstream issue that the cache causes an issue. I deleted my .eclipse directory (not sure if I even had one before on this machine), and my workspace, and I still had the same issue. So I don't think it's a caching issue. (I'm also using IcedTea). Yeah, I've fixed the tomcat symlinking and patching and have a 3.3.1.1 update for F-8 forthcoming. I just need to figure out how to do an update for icu4j and eclipse at the same time. |
