Is there a way I can make the accepted string length longer or is this something out of my control?

Go into options in launcher window and set to recommended builds. It fixed it for me.

*shamefully raises hand* Fixed it for me too.

Which launcher? I click launch and it starts my server in the cmd. No one can join because of the string size issue.

[Agent_Rourke]

In the Technic launcher.

There is a development build for 1.2.5, and if your players have "use latest development builds" selected, they will be on the completely wrong version of minecraft. You will need to tell them to open the launcher and hit the options button, from there select use recommended build.
