Description Maksim Khramov 2007-08-14 15:35:16 UTC 
Create new Java application project.
Rename Main class or move it to other package.
Run Profiler
Profiler fails with "java.lang.NoClassDefFoundError" message in output.

In case of simple project running the IDE asks for main class name before run.

Comment 2 Jiri Sedlacek 2007-08-15 16:26:19 UTC 
Actually the above exception occurs only when a Profiling Point was defined in moved/renamed class. Otherwise just the 
NoClassDefFoundError appears in Output and the profiled application is terminated.
Comment 3 Jiri Sedlacek 2007-08-21 12:15:40 UTC 
Dialog is now opened before profiling to select the main class. However, the selected main class is used only for
profiling and isn't set for the Project. Filed a RFE to implement this on j2seproject side: Issue 113321.

Fixed for Beta1.
