Hey Guys,

Im new to this forum, so if i posted under the wrong Topic, please correct me.

To the Problem:
I installed Repast Simphony (An Agent based Simulation Software)just like its descripted in the quick start Guide: repast.github.io/quick_start.html
And the i tried to start coding my first Simulation, but instantly when i create a new Class (Java) i get the Problem Message:

"An internal error occurred during: "Requesting Java AST from selection".
'boolean com.ibm.icu.text.UTF16.isSurrogate(char)'"

This only happens when im in the Skript. When i close it and only see the Package Explorer everything is fine.

I've tried a number of things like checking if the Project isnt encoded in UTF8 or ive tried to update eclipse(which failed).

Does Anyone know, what might cause this Problem, and hoh i can resolve it?

Thanks in advance
Lukas

It looks like they depend on an older version of ICU4J where that method has not been removed. So it doesn't sound like their stuff is compatible with the latest Eclipse. Maybe you should look here to ask those folks directly:
