After a major change to CVS project struture and references, one in our team couldn't run her JUnit test class any more. All attempts at running that class - and also at getting the Run/Run...-window (Launch configurations) resulted in a NPE. After several failed attempts at clearing the classpath and launch history, we noticed that one of the old history launches was able to run. After that, everything worked OK. This is the relevant part of the log file. !SESSION sep 25, 2002 10:38:42.734 --------------------------------------------- java.version=1.3.1_03 java.vendor=Sun Microsystems Inc.
