Created attachment 111666 [details] internal error trace MTJ Fails to run a MIDlet from a project with less than 3 characters as name. This error occur in the createTempDirectory method of the org.eclipse.mtj.core.internal.utils.TemporaryFileManager class on the org.eclipse.mtj.core plug-in. The method File.createTempFile(prefix, suffix, directory) throws IllegalArgumentException if the prefix argument contains fewer than three characters.
