Dave Meibusch commented on MNG-2879: ------------------------------------ I can further confirm it is an IBM JVM issue for us. We build on every platform, but IBM JVM only on AIX. mvn -version Maven version: 2.0.9 Java version: 1.5.0 OS name: "aix" version: "5.2" arch: "ppc64" Family: "unix" java -version java version "1.5.0" Java(TM) 2 Runtime Environment, Standard Edition (build pap64dev-20060511 (SR2)) IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 AIX ppc64-64 j9vmap6423-20060504 (JIT enabled) J9VM - 20060501_06428_BHdSMr JIT - 20060428_1800_r8 GC - 20060501_AA) JCL - 20060511a Build is very very slow, but haven't noticed any negative effects on build output. > Thousands of [WARNING] Component returned which is not the same manager. > ------------------------------------------------------------------------ > > Key: MNG-2879 > URL: http://jira.codehaus.org/browse/MNG-2879 > Project: Maven 2 > Issue Type: Bug > Components: Plugins and Lifecycle > Affects Versions: 2.0.6 > Reporter: Brian Fox > Assignee: Jason van Zyl > Fix For: 2.0.x > > > It happens when processing resources, mostly for war projects although I'm > not 100% positive it's only wars. We see one of these warnings apparently for > every file processed because sometimes there are just a few and sometimes > there are 1000s correlating to the number of files in the project. So far it > only happens on dual-core machines although not every time. It smells of a > multithreading issue. > This issue has already been fixed in PLX-287. This MNG issue is to try and > get that fix into 2.0.x -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
