[xwiki-devs] JAR Duplicates in 4.3 Milestone 1 and SNAPSHOT

Hello everybody, After the release of 4.3 Milestone 1, I wanted to start testing the new features but I ran into an issue ( http://jira.xwiki.org/browse/XWIKI-8365 ) when starting and accessing the Wiki based on 4.3 M1. After Marius helped me figure out the cause, it seemed that we had a jar duplication of Xalan in our Manager package. I have tested this on another machine and wasn't able to reproduce. Fabio also tested, without success, but the duplication is clear - I had 2 Xalan jars in my /lib folder (even on the machine where I had no errors). After that, I started to look for other duplicates in my /lib folder. Below are my findings. Checked these 2 XWiki packages to be sure it's not package dependant: * xwiki-manager-jetty-hsqldb * xwiki-manager-jetty-mysql Found the following JAR duplicates: 1) activation-1.1.1.jar activation-1.1.jar 2) commons-lang3-3.1.1jar commons-lang-2.6.jar 3) jdom-1.0 jdom-1.1.jar 4) plexus-utils-2.0.6.jar plexus-utils-2.0.7.jar 5) rome-0.9.jar rome-1.0.0.jar rome 1.0.jar 6) vorbis-java-core-0.1.jar vorbis-java-core-0.1-tests.jar 7) xercesImpl-2.9.1.jar xercesImpl-2.8.1.jar After the release of 4.3 M1 I have also downloaded a 4.3-SNAPSHOT build (xwiki-manager-jetty-hsqldb-4.3-20121025.181227-95.zip). Besides the duplicates from above, I have also found a lot of XWiki jars duplicated. Note, the list if far from being complete ! xwiki-commons-classloader-api-4.3-20121024.173322-34.jar xwiki-commons-classloader-api-4.3-SNAPSHOT.jar xwiki-commons-classloader-protocol-jar-4.3-20121024.173330-34.jar xwiki-commons-classloader-protocol-jar-4.3-SNAPSHOT.jar xwiki-commons-component-observation-4.3-20121024.173347-34.jar xwiki-commons-component-observation-4.3-SNAPSHOT.jar xwiki-commons-configuration-api-4.3-20121024.173413-34.jar xwiki-commons-configuration-api-4.3-SNAPSHOT.jar xwiki-commons-context-4.3-20121024.173359-34.jar xwiki-commons-context-4.3-SNAPSHOT.jar xwiki-commons-diff-api-4.3-20121024.173722-33.jar xwiki-commons-diff-api-4.3-SNAPSHOT.jar xwiki-platform-bridge-4.3-20121025.165136-181.jar xwiki-platform-bridge-4.3-20121025.174305-182.jar xwiki-platform-cache-api-4.3-20121025.165403-177.jar xwiki-platform-cache-api-4.3-20121025.174540-178.jar xwiki-platform-cache-infinispan-4.3-20121025.165428-177.jar xwiki-platform-cache-infinispan-4.3-20121025.174606-178.jar xwiki-rendering-transformation-icon-4.3-20121024.193826-57.jar xwiki-rendering-transformation-icon-4.3-SNAPSHOT.jar xwiki-rendering-transformation-linkchecker-4.3-20121024.193846-57.jar xwiki-rendering-transformation-macro-4.3-20121024.193051-57.jar xwiki-rendering-transformation-macro-4.3-SNAPSHOT.jar xwiki-rendering-transformation-wikiword-4.3-20121024.193833-57.jar xwiki-rendering-transformation-wikiword-4.3-SNAPSHOT.jar Items statistics: /lib folder on SNAPSHOT : 126.6 MB - 445 Items /lib folder on Milestone 1: 126.3 MB - 392 Items The odd thing is that I do not get any warnings, errors, stacktraces when starting the 4.3-SNAPSHOT. I wrote this mail to report the issue, because IMO this can cause serious issues. Regards, Sorin B.
