emve21 Posted October 17, 2014 Share Posted October 17, 2014 When I hit play on my technic launcher, it loads up fine and closes but then technic launcher reopens ! Below is the error in my console.

zaza7 Posted October 17, 2014 Share Posted October 17, 2014 (edited) This is a simple fix, Oracle rolled out Java 8u25 to all users 1 to 2 days ago at 12:01 AM EST. Install Java 7u67 to be able to launch modpacks from technic again. This has been discussed already here: http://www.technicpack.net/article/view/concurrentmodificationexception-in-java-18020.89 Edited October 17, 2014 by zaza7 emve21 1 Link to comment Share on other sites More sharing options...
