[jira] (MNG-5493) Concurrency exception in Maven core while using
parallel build
[ https://jira.codehaus.org/browse/MNG-5493?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Scholte updated MNG-5493:
--------------------------------
Description:
My project uses parallel build for my "deployment" job in Hudson. From time to time, the build failed because of the following {{ConcurrencyModificationException}}. This apparently is not a plugin-in bug. Instead, it is a deeper issue in the core. I checked the source code, I think the "Properties" should be replaced by a concurrentHashMap. Accordingt to the java doc of "Properties", it cannot support concurrency.
