Which build are you using ? |
When I compile this code with jdk 1.5 and deactivating (!) the "preserve unused (never read) local variables" in classfile options the generated classfile will throw an Error as ilist.next() is never called: public static void main( String[] args ) { List<String> ilist = new ArrayList<String>(); ilist.add( "Dies" ); ilist.add( "ist" ); ilist.add( "ein" ); ilist.add( "Test" ); int count = 0; for( String o : ilist ) { count++; if( count > 10 ) { throw new Error(); } } } I think this should at least give a warning.
