Sun ONE - compile OK, disaster follows; Eclipse - compile fails

Question

I hope Sylvia won't rap my knuckles with her ruler for posting an "it won't compile" message here, but this one is more than a bit strange.
I was running Sun ONE Studio. It compiles my program w/o errors; then the application runs and crashes my Windows Me computer. Reliably; repeatedly. Hard to make progress when your development cycle is compile, try to test, reboot. What to do?
Maybe the problem's in S1S! Try Eclipse. It won't compile the program. It says:
java.lang.Error: Unresolved compilation problem:
     at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
     at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source)
     at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source)
     at java.lang.reflect.Constructor.newInstance(Unknown Source)
     at jdb.FileViewer.main(FileViewer.java:120)
Exception in thread "main"
Come to think of it, that's really a compile error detected at run time, isn't it? Didn't know that was possible. Anyway, the offending line is:
  public static void main( String[] args ) {}(I simplified main() a bit trying to track this down.) If I remove main() altogether, it compiles and dies with the expected "can't find main()" error.
Anybody can make any sense of this? (BTW, kudos to Eclipse. This beats trashing my machine. There's nothing but java here - no JNI - so trashing the OS isn't even possible, is it? So much for theory.)

Exception in thread "main" Er... where exactly does Eclipse tell you this? Normally compilation diagnostics show up in the Task View. The above stack trace looks like nothing I have ever seen before when compiling. What Eclipse view is showing this message?
