Hi, I'm using JMeter r723926 (Version of 6 Dec 08). When I set up the JMeter Http Proxy Controller with a port which is already in use by another process then, although a warning is posted in the jmeter.log, there is no alert in the Gui (Http Proxy Server Controller) notifying the user about the occupied port. Especially for jMeter beginners which are not used to check the log file, an alert like the following would be very helpful: When pressing the START button of the Http Proxy Server Controller, the alert "Port XYZ is already in use, please choose a different one." is displayed. Thanks for your great work.
Created attachment 23118 [details] patch_bug46436.txt with the patch, an alert window will be shown if the proxy port is already in use. Additionally, an error log entry is written to jmeter.log
Thanks for the patch. Although the patch worked, it was still a bit confusing for the user as the Stop/Start buttons were still updated as if the proxy had started correctly. So I ended up making a more substantial change; see SVN revisisions: r737409 r737410 r737411
