["Anthony Vanelverdinghe (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NETBEANS-4477?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17259169#comment-17259169 ] 

Anthony Vanelverdinghe commented on NETBEANS-4477:
--------------------------------------------------

[~Kacer] The steps to reproduce are: (1) set up an environment like mine, and (2) code Java for 5-10 minutes. Now you can argue that the second step is too vague, but as I said in the decription:
bq. It happens frequently, but I don't have a simple recipe to reproduce.
