Description Evgeny V. Chesnokov 2005-10-08 05:43:30 EDT

Good day.
Here's the line of code:
new int[0].getClass().
when i press Ctrl+Space after that dot, i get a dialog message java.lang.
IllegalArgumentException. This also takes place for some other primitive values, 
like byte[] or char[](i didn't check all of them). All's fine for Objects and 
Object arrays. I'm using Eclipse 3.2m2. I checked this line of code in Eclipse 
3.1m7, it worked fine.
Here's the stack trace:
