Subject Re: [jira] Commented: (HARMONY-27) The network related channels in java.nio.channels are not implemented
Date Fri, 20 Jan 2006 07:03:34 GMT
Sorry for the confusion I caused, I DID write it in txt, about the "red", I
didn't mean the color of text, but the color of classes in the class diagram
I attached:). I thought I should add the attachment link to this JIRA
comments. Sorry for that.
