[jira] Commented: (MNG-4864) npe when transferring artifacts
[ http://jira.codehaus.org/browse/MNG-4864?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=239497#action_239497 ]
Benjamin Bentmann commented on MNG-4864:
----------------------------------------
The code in question:
{noformat}
for ( Map.Entry<TransferResource, Long> entry : downloads.entrySet() )
{
long total = entry.getKey().getContentLength();
long complete = entry.getValue().longValue(); // line 60
{noformat}
which suggests {{entry.getValue()}} is {{null}} which is interesting given that we iterate a {{ConcurrentHashMap}} here which doesn't allow {{null}} values.
What JRE version/vendor are you using?
