Example models won't run in NetLogo 6.0.2

[cmgoold]

I am running NetLogo version 6.0.2 on a Linux machine. I have installed the time extension but the example models that I have tried (e.g. the mouse trap model) will setup but not run. The error message I receive is below. Thanks for your help!

hi, is this issue fixed? how reliable this extension is? I am interested to apply some forms of discrete event modelling paradigm inside my ABS model using Netlogo

[robwalton]

The issue still exists with netlogo 6.1. I've tried it with netlogo 6.0 and there is no problem. When using netlogo > 6.0 netlogo reports that the extension was built against 6.0 and may not work. I'll try rebuilding it against 6.1 and see what happens.

For reference, the exception reported above

java.lang.IllegalAccessError: tried to access field org.nlogo.agent.World.tickCounter from class time.datatypes.LogoSchedule

occurs with the following when calling time:go:
