Can't debug with JDK1.3.1_07 in build#695 Follow Jason Hao Created March 01, 2003 06:36 We know that jdk1.3.1_07 is out. Unfortunately, it cann't start debug session in IDEA! It always says 'java.lang.NoClassDefFoundError: Exception in thread "main"'! But jdk1.3.1_06 or j2sdk1.4.1_02 is ok. Anyone knows why?
