I am running Omnet 4.2.2 on an Ubuntu 12.04 laptop. I compiled and installed 6 months ago and was working until now.

Today when I was editing an omnetpp.ini file in one of my simulations, the IDE crashed. Whenever I try to start it, it always crashes.

I thought that the crash had to do with the .ini file, so I emptied the contents, renamed and deleted the file, but with no improvement.

I tried to delete the .metadata files of the workspace. Then, when the IDE loads, I get a fresh and empty workspace. I imported an existing project. When I try to compile or run it, I get a bunch of messages like these ones:

############### <ERROR MESSAGES> ###############

An error has occurred. See error log for more details.

Could not initialize class com.ibm.icu.impl.JavaTimeZone

An internal error occurred during: "Compute launch button tooltip".

org/eclipse/cdt/core/model/CoreModel

############### </ERROR MESSAGES> ###############

I am not sure what to do. I recompiled omnet, in a new installation, but when I try to open my workspace, same things happen. The problem is either in my system or in my workspace. The best hint would be to create a new workspace and add my projects, but as I said above, it fails.

In the end of the mesage, I attach the .metadata/.log file with the java errors upon crashing.

I would appreciate your out-of-the-box thoughts (-:
