[ https://issues.jboss.org/browse/JBIDE-21463?page=com.atlassian.jira.plugi... ] Viacheslav Kabanovich commented on JBIDE-21463: ----------------------------------------------- We can add validation of local ports, if they are in use. It seems to be quite a fast operation. The following code, checking all 65536 ports for availability: {code} for (int i = 0; i < 65536; i++) { try { new ServerSocket(i).close(); } catch (IOException e) { System.out.println("Port " + i + " is in use"); } } {code} runs less than one second. We have to check only few ports, and show an error status listing those in use. When port forwarding is started, we can either not check ports at all, or check that they _are_ in use, and if not, show warning status listing ports that should be in use but are not. [~adietish], do you think that may be ok? -- This message was sent by Atlassian JIRA (v6.4.11#64026)
