Issue with protocols after Icy upgrade


first of all thanks for the new version V2.1.0 of Icy!
However, opening the protocol editor leads to an error (see below). The same happens with a fresh install. For now I can go back to V2.0.3


OpenJDK Runtime Environment 1.8.0_265-b01 (64 bit)
Running on Windows 10 10.0 (amd64)
Number of processors : 8
System total memory : 20.8 GB
System available memory : 11.1 GB
Max java memory : 10.6 GB

VTK 6.3.0 library successfully loaded...

Icy Version started !

An error occured while plugin 'Protocols' was running :
java.lang.NoClassDefFoundError: com/ochafik/io/JTextAreaOutputStream
	at icy.plugin.abstract_.PluginActionable.compute(
	at icy.plugin.PluginLauncher$
	at icy.plugin.PluginLauncher$
	at icy.system.thread.ThreadUtil.invokeNow(
	at icy.plugin.PluginLauncher.internalExecute(
	at icy.plugin.PluginLauncher.start(
	at icy.gui.plugin.PluginCommandButton$2.actionPerformed(

I’ve experienced the same issue. Being my first time using Icy I figured it was sometihng I had done with Java settings. Thanks for the idea to go to a previous version.

Dear Gucki, Dear Nobes1,

Thank you for reporting this bug. I can reproduce it on my computer.
I transmitted the bug report to our developers. For the moment, please go back to version

Best regards,

Hi all,

Sorry for the troubles ! This new version brings many internal changes and unfortunately we forgot to add a small dependency to Protocols plugin on the website. It’s fixed now so if you force updates in Icy you should see the new Protocols version that fix the issue :wink:
