RE: Java app and Native Processes on Linux

Hi:   I'm trying to use two java threads t1 and t2, and each one uses exec() to start the same C native application.  It seems JVM (BlackDown 1.1.8 v1) never switches from t1 to t2.  The output looks like:   In thread t1: i = 0 In thread t1: i = 1 In thread t1: i = 2   ...   I put s
