After changing azureus.gentoo to use the console ui, azureus does not use the console ui. I found that the /usr/bin/azureus script has some errors, mostly likely caused by the changes in the how java works on gentoo recently. Here are the required fixes in /usr/bin/azureus: 1.) change gjl_main to "org.gudy.azureus2.ui.common.Main" on line 2. 2.) add "--ui=${UI}" to the last line, making it: source /usr/share/java-config-2/launcher/launcher.bash --ui=${UI} Those two changes fix the problem.
Fixed in 2.5.0.0-r1. Thanks for the report.
